Sleeping and Studying
Sleeping and Studying 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 ...

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: 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 ...

How does resonance stability work in organic compounds?
Resonance stability in organic compounds refers to the stabilization that arises from the delocalization of electrons within a molecular system. It occurs in compounds with conjugated systems, where pi electrons can move or be shared over multiple atoms or bonds. This delocalization of electrons leads to increased stability due to the spreading of charge or electron density. Here's how resonance stability works: Conjugated Systems: Resonance stability primarily occurs in compounds with conjugated systems, which involve alternating single and multiple bonds or the presence of lone pairs of electrons adjacent to a pi bond. Examples include benzene rings, allylic systems, and carbonyl compounds. In these systems, the p orbitals overlap to form a continuous network of pi bonds along the molecule ...

Differences between H2 and H3 Chemistry
Overview H3 and H2 subjects in Singapore's Junior College (JC) curriculum differ in terms of syllabus, content, and level of difficulty in assessment. H3 subjects are considered more challenging than H2 subjects, as they are typically designed for students who have a strong interest and aptitude in a particular subject area. These subjects usually have a more advanced syllabus and require students to have a deeper understanding of the content. H3 subjects also tend to have more demanding assessment criteria and may include additional coursework or research components. H2 subjects, on the other hand, are considered to be of a lower level of difficulty and are typically taken by students who want to study a subject in more depth, but ...
Changes in GCE ‘A’ level Education
Changes in GCE 'A' level education Source: https://www.channelnewsasia.com/singapore/mid-year-exam-junior-college-jc-millennia-institute-ministry-education-3311161 Headlines: No more Mid-Year examinations General Paper made compulsory Project Work becomes a pass/fail subject University Admission Score will be rebased to 70 from 90 1)     Some thoughts regarding the scraping of mid-year exams - less administrative work to prepare for a major exam, more time to put back into lessons and learning. But, like what many others have already pointed out, without this major milestone check, students will be in for a rude shock when it comes to their End of Year Exams. "The removal of mid-year examinations will not be replaced (emphasis mine) by more school-based assessments, and JCs and MI must not administer more than one weighted assessment ...
Transition Element (Common Last Topic)
Annoucement Minister Chan just announced on 27th July 2021 that the common last topic will be taken out of the A levels examinations this November. For those of us who already did the topics, it seemed like time was wasted to teach this topic. But the good thing is students will have less to revise this year. Rightfully so as the multiple disruptions due to tightening/loosening covid measures surely affected the students' ability to focus. With the time now freed up from revising transition elements, we can now focus on the topics that are left. For those of you who have not done up a revision schedule, now is the best time to plan it. IMHO, A levels is not ...
Tang Ping
Tang Ping Read an article about a trending movement from China/Hongkong called "Lying flat".⁠ ⁠ Reading the articles makes me think, this is the other extreme of the FIRE 🔥 movement. But rather then working really hard and saving almost all of your take-home pay so that you can reach financial independence much earlier and retire early, Lying Flat movement simply adopts a monastic mindset.⁠ ⁠ Don't get married 🤵🏻👰🏻, don't have kids, don't buy a car and don't buy a flat. Just do the minimal work to get by. Some take it to extremes and don't even socialize in order to save money.⁠ ⁠ The underlying (no pun intended) worldview is one of killing all desires so that you ...
Transition Elements
Transition Element Last year due to Covid 19, we did not cover the common last topic, which was Transition Element. This year, i was waiting for some announcement from SEAB to see whether TE would be tested in A levels this Nov. Alas, the announcement never came. In the absence of any official announcements, i guess we would have to cover this common last topic this year. Hopefully, SEAB wouldn't change its mind at the last minute and say it will not test TE. Very likely this trend of Circuit breaker and calibrated re-opening will continue for a good 2-3 years. Will need to plan ahead so that disruptions are minimize as much as possible. Mr Khemistry will be moving ...
