Study Strategy

Mr Khemistry

Study Strategy for graduating students (O and A levels)

If you are taking the national exams at the end of the year, you need to listen up. Half of the academic year has passed, so has all the CCA and SYF commitments. Your attention should be focused squarely on catching up on your revision using the correct study strategy.

A common refrain i hear from parents is that their children is studying hard and late into the night, but is still failing their tests and exams.

Doesn’t hard work promise good results? So why are they still failing?!

Most students are studying for their exams the wrong way. They are reading through their lecture notes or textbooks and trying to understand and HOPEFULLY apply those complex concepts.

This is akin to going for a piano exam, after reading a book on how to play piano. It’s going to be a disaster.

The most effective revision is to PRACTISE past year questions and APPLY the concepts. A lot of students practise doing their tutorial WHILE referring to their lecture notes/textbook. There’s two fatal mistakes here. In exams, you can’t refer to the notes or textbook and you have to complete the questions under timed constraints.

This group of students most likely struggle to pass their tests, scoring below 45 marks.

What’s the most effective study strategy to use?

Doing past year questions without referring to notes under timed constraint of course! 

But not many students will do that as they feel that they will not be able to do ANY questions. A compromise will be they refer to their notes for the first few questions and take note of what are the parts they couldn’t do by themselves. Then after a few questions with reference, they can proceed to attempt the questions without referring to the notes. Finally, once they get the hang of it, they should practise doing the questions under timed constraint.

Even after practising after timed constraint, students would need to mark their work and check for missing key marking points.

If they can do that consistently for all topics and content subjects (science/math), they will be in a much better position going into the exam.

Tuition Industry Evolution in Singapore Post-COVID-19

Mr Khemistry

Singapore’s tuition industry has long been a prominent feature of the education landscape, catering to the needs of students striving for academic excellence. However, the COVID-19 pandemic brought about significant disruptions, forcing the industry to adapt rapidly. In this article, we explore how the tuition industry in Singapore has evolved in the aftermath of the pandemic, transforming teaching methods, embracing technology, and addressing the changing needs of students.

Shift to Online Learning

One of the most noticeable changes in the tuition industry post-COVID-19 has been the rapid adoption of online learning platforms. With the closure of physical tuition centers during lockdowns, educators swiftly transitioned to virtual classrooms to ensure continuity in education. Online platforms and video conferencing tools became the new norm, allowing tutors to deliver lessons remotely while ensuring the safety of students.

Tuition - Online student portal

Screenshot of Mr Khemistry’s online student portal                                                                                                       

However, during the transition, tutors faced several challenges that required them to adapt quickly to the new teaching environment. Some of these challenges include:

  1. Technical Difficulties: Tutors had to navigate through technical issues such as unstable internet connections, audio or video disruptions, and software compatibility problems. These technical difficulties could disrupt the flow of the lesson and hinder effective communication between the tutor and the students.
  2. Limited Non-verbal Cues: In a physical classroom, tutors rely on non-verbal cues like facial expressions and body language to gauge student understanding and engagement. However, these cues may be limited or difficult to interpret in an online setting. This makes it challenging for tutors to gauge the students’ level of comprehension or address any confusion immediately. Establishing a rapport and connection with students is crucial for effective teaching and learning. Tutors faced the challenge of building and maintaining meaningful relationships with their students in an online setting. The absence of face-to-face interactions made it more challenging to establish a personal connection and create a supportive learning environment.
  3. Adaptation of Teaching Methods: Tutors accustomed to traditional teaching methods had to quickly adapt their pedagogical approaches to suit the online environment. They had to explore new strategies to deliver content effectively through digital platforms.

Online learning can present distractions and reduced attention spans for students. Tutors had to find innovative ways to keep students engaged throughout the lesson, as the lack of physical presence and potential distractions at home could impact their focus and participation. Tutors have employed various innovative strategies to keep students engaged during online lessons.

Innovative strategies

  1. Interactive Presentations: Tutors have utilized dynamic and interactive presentations using multimedia tools, such as videos, animations, and interactive quizzes. These engaging elements help capture students’ attention and make the learning experience more enjoyable and interactive. They have used educational games, quizzes, and competitions to motivate students and foster healthy competition while reinforcing learning objectives. One example is Kahoot! MCQ quizzes which helps to engage the online students and assess their understanding in a fun and casual manner.
  2. Real-life Applications: Tutors have made efforts to relate the content to real-life applications and examples, making the lessons more relevant and relatable to students. By demonstrating how the concepts they are learning can be applied in practical situations, tutors enhance student engagement and understanding. One recent example we used was a demonstration of the solubility of salts, students were excited to see real-life application of what they have just learnt in theory.
  3. Virtual Whiteboards and Annotation Tools
    We have utilized virtual whiteboards and annotation tools during Zoom online lessons to facilitate real-time explanations and demonstrations. These tools allow tutors to write, draw, and highlight important points, enabling students to follow along and actively participate in the lesson. Zoom also allows recording of lessons and learning management systems like Teachable allows unlimited uploads of video recordings for students to refresh their concepts as and when it’s required.
  4. Chat feature in zoom encourage student interaction and participation. We pose questions, initiate discussions, and gather student feedback through these features, promoting engagement and active involvement.

By employing these innovative strategies, our tutors have been able to create dynamic and interactive online learning environments. Thus ensuring that students remain engaged, motivated, and actively involved in their education.

Flexible Learning Schedules:

The pandemic has reshaped the way students manage their time and commitments. With the implementation of remote learning, tuition providers have adapted their schedules to accommodate the changing needs of students. Online platforms have allowed for greater flexibility, enabling students to attend classes at their convenience. This flexibility has been particularly beneficial for students who previously struggled with juggling multiple commitments, allowing them to strike a better work-life balance.

Expansion of Small Group Tutoring:
While one-on-one tutoring remains popular, small group tuition has gained traction post-pandemic. Small group sessions provide students with the opportunity to collaborate and engage in peer-to-peer learning, fostering a sense of camaraderie and healthy competition. These sessions also allow tutors to manage their time more efficiently, catering to multiple students simultaneously while still providing individual attention when needed.

Emphasis on Well-being and Holistic Development:
The pandemic has underscored the importance of holistic development and mental well-being. Tuition centers have recognized this shift and are increasingly incorporating elements of emotional support and stress management in their programs. Beyond academic excellence, tutors are now equipped to provide guidance on managing anxiety, building resilience, and maintaining a healthy work-life balance. This holistic approach aims to support students’ overall growth and well-being, ensuring they thrive academically and emotionally.

Conclusion:

The COVID-19 pandemic has undoubtedly accelerated the transformation of the tuition industry in Singapore. While the challenges it presented were significant, the industry has emerged stronger, adapting to new teaching methods. As we move forward, the tuition industry will continue to play a vital role in supporting students in their academic journey.

Getting a strong start for H2 Chemistry in 2024

Mr Khemistry

To get a strong start in H2 Chemistry in 2024, here are some steps you can follow (things NOT to do are in parentheses) :

  1. Review foundational concepts: Start by reviewing the foundational concepts from J1 Chemistry or the main topics you have weakness in. Make sure you have a solid understanding of topics like atomic structure, chemical bonding, chemical equations, stoichiometry, and periodic trends. (Don’t review/revise if you want to be like everyone else, failing)
  2. Familiarize yourself with the syllabus: Obtain a copy of the H2 Chemistry syllabus for 2024 and go through the learning objectives carefully. Understand the topics that will be covered in J2 and the specific learning outcomes expected from you. This will help you plan your study schedule effectively. For H2 Chemistry in J2, usually you will need to practise mindmaps for organic chemistry thoroughly. (ALL students who fail don’t remember reagents and conditions, so if you want to fail, don’t memorise reagents and conditions for organic chem)
  3. Set clear goals and create a study plan: Break down the syllabus into smaller topics and allocate time for each based on their weightage and your familiarity with them. Create a study plan that includes regular study sessions, revision periods, and practice questions. For our current system of assessment, one of the best ways to practise is to get hold of past year test papers from your college and do it under timed conditions. Mark your work and review your mistakes. You will soon notice a pattern how the questions are crafted. (Do not attempt “open book” practise where you refer to your notes and not keeping to timed conditions. Many students do their tutorials and ten year series this way and wonder why they still fail. In exams settings, there is no answers for you to refer to while attempting the questions. Remember that.)
  4. Use reliable study resources: Gather high-quality study resources, including textbooks, reference books, online resources, and past examination papers. Look for resources that are recommended by your teachers or trusted sources. These resources should provide clear explanations, examples, and practice questions to reinforce your understanding. OR…you can use our in-house notes, carefully curated to the H2 chemistry learning objectives. Do check out our class schedule to find your preferred timeslot! Ok, end of commercial 🙂 (Students who fail usually have incomplete notes or notes with lots of mistakes)
  5. Attend classes and engage with the teacher: Actively participate in your H2 Chemistry tutorials. Take notes, ask questions, and clarify any doubts you may have. Yes, this means you will have to PREPARE BEFOREHAND! Don’t go to tutorials like going for a movie, waiting to be entertained! Engage with your teacher and classmates in robust conceptual discussions to deepen your understanding of the topic. Make use of the opportunities to perform experiments in the laboratory and understand the practical aspects of chemistry….instead of just blindly following what your friends are doing. (Many students go to practical lessons not knowing what they are doing, don’t let it be you.)
  6. Practice regularly: Chemistry requires practice to develop problem-solving skills and reinforce concepts. Solve a variety of practice questions, including those from tutorials, tests and past papers. Pay attention to the steps involved in solving problems and try to understand the underlying principles. Practicing regularly will help you identify areas where you need improvement.(What NOT to do – keep referring to the solutions to get the answer and not knowing how to solve a similar question.)
  7. Form study groups: Consider forming study groups with classmates who are also committed to excelling in H2 Chemistry. Collaborating with others can help you gain different perspectives, share knowledge, and clarify doubts. Discussing challenging topics and solving problems together can enhance your understanding and retention of the subject matter. I know some students have very active daily discussions with their classmates and teachers in a whatsapp chat group. This helps every one to think through the problem and understand how to follow a thought process. Teachers do this very often, that’s why we often know what the question will ask before we read the whole question stem. (students who fail don’t participate in active daily discussions)
  8. Seek help when needed: Don’t hesitate to seek help when you encounter difficulties. Reach out to your teacher or classmates for assistance. If necessary, consider hiring a tutor who specializes in H2 Chemistry to provide additional guidance and support. Sometimes it is difficult to reach your school teachers after office hours, or when you are doing your tutorials or assignments. Once again, if you are looking for an experienced, reliable H2 chemistry tutor, contact us at 83322534 🙂 (remember students who fail, most of them don’t ask questions in class because they don’t prepare for tutorial)
  9. Stay organized and manage your time effectively: Maintain a well-organized study environment and keep track of your assignments, deadlines, and important dates. Use a planner or digital tools to manage your time effectively and prioritize your tasks. I use a weekly planner every year to plan out to-do lists, keep track of process, reflections etc. There are just so many things we can put on the planner, as they say, “On the paper, off the mind”. “Thoughts disentangle when they pass through the fingers”. Facts: Things that you write out have a much higher possibility of getting done! (Fun fact, students who fail tests sometimes didn’t even know there was a test until just before it!)
  10. Stay motivated and take care of yourself: H2 Chemistry is a challenging subject, don’t let anyone tell you it’s so easy. It’s essential to stay motivated and take care of your mental well-being. Set small milestones and reward yourself when you achieve them. Take breaks during long study sessions to relax and rejuvenate. (But don’t game in the middle of studying, it breaks your focus.) Get enough sleep, eat nutritious food, exercise regularly, and maintain a healthy study-play balance. A tightly knit community can journey with you through this season. Remember, consistency and perseverance are key to success in H2 Chemistry. May you find good success in H2 Chemistry!

This will help you become familiar with the types of questions asked, the level of difficulty, and the time pressure you may experience during the actual exam. Analyze your answers and identify any patterns of mistakes or weaknesses. This is particularly crucial as students tend to be weak in certain areas, e.g. calculations.
  4. Learn from Mistakes: When reviewing your practice MCQs, carefully analyze the questions you answered incorrectly. Understand why you made the mistake and learn from it. Review the underlying concept or topic related to the question and reinforce your understanding to avoid similar mistakes in the future.
  5. Focus on Explanations: MCQ papers often provide explanations or solutions for the questions. Pay close attention to these explanations, even for questions you answered correctly. This will help you deepen your understanding and gain insights into the reasoning behind the correct answers. Many students skip this part because they think they’ve already understood the concept when in fact they just happened to pick the correct answer.
  6. Identify Common Patterns: MCQs often follow certain patterns or trends. Identify common question types, such as those related to specific reaction mechanisms, common misconceptions, or applications of key concepts. By recognizing these patterns, you can better anticipate the types of questions that may appear in the exam and prepare accordingly.
  7. Practice Quick Analysis: Train yourself to quickly analyze each question. Read the question carefully, identify the key information, and eliminate any obviously incorrect options. Use your knowledge and reasoning skills to narrow down the choices and select the most appropriate answer. Remember to consider all the given options before making your final selection.
  8. Develop Test-Taking MCQ Strategies: In addition to content knowledge, develop test-taking strategies to maximize your performance during the exam. For example, if you’re unsure about an answer, use strategies like educated guessing or strategic elimination to increase your chances of selecting the correct option. This is especially useful for those questions that involves identifying a correct sequence. Any part that does not have a correct sequence can be eliminated first.
  9. Time Management: During your practice sessions, ensure that you allocate a specific amount of time for each question. This will help you develop a sense of timing and ensure that you can complete the paper within the given time frame. If you encounter a particularly challenging question, it’s better to move on and come back to it later if time permits. The general strategy for H2 Chemistry is to do the organic questions faster and allocate more time for complex calculation questions.
  10. Seek Feedback: Consider seeking feedback from your Chemistry teacher or peers. They can review your practice papers, provide insights on your performance, and offer suggestions for improvement. Peer discussions can also be beneficial as you can learn from each other’s approaches and thought processes.

Should I get a MOE teacher or non-MOE tutor?

Mr Khemistry

Hiring a Ministry of Education (MOE) teacher or a non-MOE teacher can have various pros and cons. Here are some factors to consider:

Pros of hiring an MOE teacher as a tutor:
  1. Expertise in the Singapore education system – MOE teachers have extensive knowledge and experience in the local education system, curriculum, and syllabus. They are well-versed in the teaching methods and assessment formats used in schools, which can be beneficial when providing tutoring aligned with the student’s school requirements. Especially for A levels Chemistry, where phrasing of the answers needs to include certain key words and terms.
  2. Familiarity with MOE resources – MOE teachers have access to a wide range of resources, including textbooks, past examination papers, and teaching materials developed by MOE. They can leverage these resources to provide targeted and comprehensive support to students. There is a difference between the resources found online and the resources an ex-MOE teacher has.
  3. Updated knowledge – MOE teachers undergo regular professional development and training sessions to stay updated with the latest teaching methodologies and curriculum changes. This ensures that their knowledge and teaching techniques are current and aligned with educational standards. Every year, MOE teachers are updated with the latest marker’s comments from Cambridge, highlighting the most common misconceptions and key phrases they deem as important.
  4. Classroom management skills – MOE teachers are experienced in managing classroom dynamics and handling diverse student needs. They often possess strong classroom management skills, which can be valuable in maintaining an effective learning environment during tutoring sessions. Note that this is only applicable for group tuition.
Cons of hiring an MOE teacher as a tutor:
  1. Limited availability and higher demand – MOE teachers may have limited availability for tutoring due to their existing teaching commitments. Additionally, their expertise and reputation may make them more in demand, leading to potential scheduling conflicts or difficulty in securing their services. Important to know that very good tutors are often fully booked by May period and their rates are typically much higher than those found by tuition agencies.  This is especially true for H2 Chemistry where the pool of qualified MOE tutors is very limited.
  2. Lack of individualized attention – MOE teachers are accustomed to teaching larger classes and may have limited experience providing one-on-one attention. As a result, they may struggle to adapt their teaching style to the specific needs and learning pace of an individual student during tutoring sessions. Not all MOE teachers are excellent private tutors, at the end of the day, it still depends on the learning style of the student and the teaching style of the tutor.
Pros of hiring a non-MOE teacher as a tutor:
  1. Flexibility and availability – Non-MOE teachers often have more flexible schedules and can dedicate more time to tutoring. They may be more readily available to accommodate the student’s preferred timing and frequency of sessions. This is especially true for non-NIE trained full-time tutors. They are more able to meet your schedule and availability.
  2. Tailored teaching approach – Non-MOE teachers can offer a personalized teaching style that caters to the student’s specific learning needs. They may have more freedom to tailor their teaching methods, pace, and content to suit the student’s requirements, promoting a more individualized learning experience. Note that this is true only for private 1-1 tuition.
  3. Specialized expertise – Non-MOE teachers may have specialized knowledge in specific subjects, teaching methodologies, or educational approaches beyond the standard MOE curriculum. This expertise can be valuable for students seeking additional support in specific areas or pursuing alternative learning paths. Probably for students in non mainstream courses, private non-MOE tutors might be more suitable.
Cons of hiring a non-MOE teacher as a tutor:
  1. Limited knowledge of local curriculum and assessment – Non-MOE teachers may not be as familiar with the intricacies of the Singapore education system, including the specific curriculum and assessment formats. They might not have access to official MOE resources, which could limit their ability to align their teaching with school requirements.
  2. Variable teaching quality – Unlike MOE teachers, who undergo stringent selection and training processes, the quality of non-MOE teachers can vary significantly. It is important to thoroughly assess the qualifications, experience, and teaching track record of non-MOE tutors before hiring them to ensure their competence and effectiveness. For this reason, it is often a hit-and-miss hiring private tutors from tuition agencies. Usually if parents are financially constrained and the student is self-motivated, attending a group tuition early in the year taught by a MOE trained teacher is preferable.

Ultimately, the choice between hiring an MOE teacher or a non-MOE teacher as a tutor depends on the individual student’s needs, preferences, and specific subject requirements. It is advisable to consider factors such as teaching expertise, availability, and compatibility with the student’s learning style when making a decision.

Inorganic QA

Mr Khemistry

Inorganic QA

Inorganic QA is one of the most feared components besides planning question for H2 Chemistry practical.

QA inorganic chemistry

Here’s a useful framework you can use to approach this part of the practical assessment.

  1. Preliminary observations: Begin by making preliminary observations of the sample, such as color, odor, and physical state. These observations can provide initial clues about the composition of the sample.
  2. Group separation: In inorganic QA, ions are often grouped based on their solubility properties. The sample is typically divided into different fractions by adding specific reagents (eg adding NaOH or ammonia to test for metal cations) to selectively precipitate or dissolve certain groups of ions. This step helps to simplify the analysis process.
  3. Confirmatory tests: Once the ions are separated into different groups, you can perform specific confirmatory tests to identify the presence or absence of particular ions within each group. These tests typically involve the addition of reagents that produce characteristic color changes, precipitates, or gas evolution reactions. For example, if you are told there is certain anions in the group, you can add silver nitrate to test for halide ions, or barium chloride to test for sulfate ions etc. Take care NOT to add sulfuric acid then test for sulfate ions (i.e. don’t add reagents with the ions you are testing for!)
  4. Observations and data analysis: Record your observations carefully during the confirmatory tests. Note any color changes, precipitate formations, gas evolution, or other reactions that occur. Compare your observations with known reactions and expected results to draw conclusions about the presence or absence of specific ions. Usually you need to have an idea what type of reaction has probably happened, e.g. if you add KI and you see a brownish suspension, a redox reaction likely occurred. The brown solution formed is likely iodine with a white precipitate of copper iodide. You should let the suspension settle for 5 mins so that you can see a brown solution and white precipitate at the bottom of the test-tube. Deduction: copper 2+ ion present.
  5. Systematic analysis: Follow a systematic approach to analyze each group of ions individually. Perform confirmatory tests for each group, taking into account any observations or results obtained in the earlier steps. Continue narrowing down the possibilities until you have identified all the ions in the sample. Use precipitation to separate cations into filtrate and reside then conduct addition test. Eg. adding ammonia to copper ions will produce blue precipitate, then adding excess will cause the blue precipitate to dissolve into deep blue solution, adding acid dropwise will reform the blue precipitate.
  6. Verification and cross-checking: After completing the analysis, it is essential to verify the results and cross-check them to ensure accuracy. Review your observations, data, and conclusions to confirm that they are consistent and logical. Look for any inconsistencies or errors that may have occurred during the analysis process. (see point 3 above)

Hope this framework has been helpful to your revision!

Adequate sleep is crucial for memory consolidation, which is the process of transferring new information from short-term memory to long-term memory storage. Here’s why sleep is important for memory:

1. Memory Formation: During sleep, the brain consolidates and organizes newly acquired information, strengthening the connections between neurons. This process helps convert short-term memories into more stable and long-lasting memories.

2. Hippocampus Function: The hippocampus, a brain region involved in memory processing, plays a vital role during sleep. It replays and reinforces the neural pathways related to the information learned during wakefulness, leading to memory consolidation.

3. Memory Stabilization: Sleep helps stabilize memories by protecting them from interference. During sleep, the brain filters out irrelevant information and strengthens important memories, preventing them from being overwritten or forgotten.

4. Learning Enhancement: Sufficient sleep enhances learning and cognitive performance. It improves attention, concentration, and problem-solving abilities, making it easier to acquire new information and store it effectively in memory.

5. REM Sleep and Memory: Rapid Eye Movement (REM) sleep, the stage of sleep associated with vivid dreaming, is particularly important for memory consolidation. REM sleep is linked to emotional memory processing and creative problem-solving, further enhancing memory retention and integration.

6. Sleep Deprivation and Memory Impairment: Insufficient or poor-quality sleep can have detrimental effects on memory. Sleep deprivation disrupts the consolidation process, leading to difficulties in retaining and recalling information. It can also impair attention, focus, and overall cognitive functioning, hindering learning and memory retrieval. See related article.

To optimize memory and cognitive performance, it’s recommended to prioritize regular, quality sleep. Aim for at least 7 hours of sleep per night, establish a consistent sleep schedule, create a conducive sleep environment, and practice good sleep hygiene habits. These practices can help support optimal memory formation and retention. This is why Sleeping and Studying are intertwined 🙂

How to study Chemistry effectively?

Study Chemistry Tips!

Studying H2 chemistry effectively requires a combination of proper planning, active learning strategies, and consistent practice. Here are some tips to help you study chemistry effectively:

  1. Understand the concepts: Start by thoroughly understanding the fundamental concepts of H2 chemistry. Take the time to read your textbook or any supplementary materials, and make sure you grasp the underlying principles before moving on to more complex topics. For example, if you don’t understand chemical bonding, it might be more difficult to understand delocalisation and resonance in Organic Chemistry later on. Another example is if you do not grasp Chemical Equilibrium’s basic concept of how equilibrium shifts according to Le Chatelier’s Principle, you will likely struggle with Acid-base Equilibrium since there’s another layer of concept (acids and bases) on top of the equilibrium concept.
  2. Create a study schedule: Plan your study time and allocate specific periods for H2 chemistry. Break down the topics into manageable chunks and assign dedicated study sessions for each. A consistent study schedule will help you stay organized and ensure that you cover all the necessary material. I keep a daily to-do list and cross them out as i go through the day. It’s extremely satisfying for me and irks me when i see many items still on the list by noon. So use a little bit of psychology here. Same concept with a door half-close, a dessert with a bite left, a circle not closed. A to-do list is an open loop and we instinctively want to close the loop by completing the tasks. If you’re the sort that can’t be bother to close the fridge door, just stop reading here already.
  3. Take thorough notes: While studying, take detailed notes that summarize the key concepts, definitions, and examples. Writing down the information helps reinforce your understanding and serves as a useful reference for revision. I have had students who are always asking me how to study better, how to score good grade etc. I wish they can see how they act when in class. Spacing out, not taking down corrections, notes when i’m teaching, not doing homework….the list goes on. There’s no magic pill to improvement, you have to do the work. You have to use your mind to think and not always trying just to memorise everything. Our brain remembers things that makes sense or have sequence, logic. If you don’t understand how the concepts works and just rote learn, there’s a limit to how much you can remember.
  4. Practice regularly: Chemistry is a subject that requires practice. Solve a variety of problems, including textbook exercises, past exam papers, and additional practice questions. This will help you apply the concepts, improve problem-solving skills, and familiarize yourself with different types of questions. Practise with your mind engaged, remember the brain is like a muscle, the more you apply it, the stronger it gets. Conversely, the less you use it…
  5. Seek clarification: Don’t hesitate to seek clarification when you encounter difficulties or have questions. Consult your teacher, classmates, or online resources to get a better understanding of challenging topics or concepts. There is so much resources nowadays, make an effort to get help. But before you go ask for any help, make sure you help yourself by doing the afore mentioned points first.
  6. Use visual aids: Chemistry often involves complex structures and reactions. Utilize visual aids such as molecular models, diagrams, and charts to visualize and understand the concepts. This can make abstract ideas more tangible and easier to comprehend. i.e. molecular models help visualize stereoisomerism.
  7. Form study chemistry groups: Collaborating with classmates can be beneficial for discussing concepts, solving problems together, and sharing different perspectives. Explaining concepts to others can deepen your understanding, and group discussions can help reinforce learning. There are many types of study groups, make sure your study group has people of different abilities. If you’re just huddling with your close friends, none of whom have the faintest idea how to solve chemistry problems, you are not going to improve studying together. It’d just be a group chit-chat session.
  8. Review and revise: Regularly review your notes and practice materials to reinforce your understanding of the topics. Use techniques like flashcards, concept maps, or summarizing key points to aid in retention and recall. I cannot begin to tell you how many students think that going to school/tuition and just sitting there copying whatever is on the screen is going to help them ace the A levels. They spend a couple of hours just reading through the lecture notes and comfort themselves that they have done enough. Nooooooo, far from it. Practise and revise regularly!
  9. Seek additional resources: Explore additional resources like online tutorials, videos, interactive simulations, or chemistry-related websites to supplement your learning. These resources can provide alternative explanations and examples to enhance your understanding. These can come in the form of tuition or textbooks also. Do check out our helpful H2 Chemistry Summaries at our student portal,  available for just $9.90! Chemistry Student Portal
  10. Stay engaged and motivated: Maintain a positive mindset, stay motivated, and find ways to stay engaged with the subject. Motivation can come from many sources, i personally use Youtube to listen to motivational talks from Jim Rohn, Tony Robbins, Lewis Holmes, etc. You can check out my Youtube channel here! Connect the chemistry concepts to real-life applications, stay curious, and appreciate the relevance and beauty of chemistry.

Remember, effective studying is about consistent effort, active engagement, and understanding the underlying principles. Be patient with yourself, seek help when needed, and celebrate your progress along the way.
