Procrastination
Procrastination. It's the one silent killer that kills all our best intentions. Why do we always wait until it's too late? Prevention is better than Cure, but nobody believes it. It's the same with health, studies, career, relationships, income/sex inequalities, even global warming. We wait until the symptoms can no longer be ignored. A stroke, heart attack, diabetes, high cholesterol. Failing grades, retrenchment, divorce, societal unrest/revolt, rising sea levels, crazy weather storms. What do all these things have in common? Their decline is unnoticeable, minute. A slow boiling of the frog. And our adaptability works against us here. Mel Ribbons gives a great interview here with Tom Bilyeu about how we can stop procrastination. One of the best habits i ...

Clarity
Clarity You might have heard the advice, "Work harder, practise more, listen attentively to lecture...." What i'm going to share is mindblowing. All those advice is good but diligence without clarity is nuts! I'm going to give a sports analogy. Soccer - Most teams will have the manager or coach give them a strategy briefing on how to play the game against the opposing team before the actual match. Why? Isn't more practise and training enough? Strikers know how to score, defenders know how to defend, midfielders know how to tackle and get possession. Goalkeeper just keep the ball out of the net. Of course not, soccer is a team game. The players need to know the objective so that ...

Sleep and memory retention
Learning and memory retention "During sleep, pathways form between nerve cells (neurons) in your brain that help you remember new information you've learned. Sleep deprivation leaves your brain exhausted, so it can't perform its duties as well. You may also find it more difficult to concentrate or learn new things." - healthline.com Guys who go to gym knows the importance of rest days, our physical body needs to rest in order to build up new muscles. If you keep gyming 7 days a week non-stop, pumping iron, without giving your body time to rest, it's actually detrimental to your body. In the same way, when you keep studying non-stop, deep into the night, getting less than 6 hours (JC students probably can't get 9 hrs as recommended!) ...

Organized Learning
Recently i had a chat with one of my top students, she said something which surprised me. "Chemistry is really simple. Especially Organic. Just need to remember the reagents and conditions, or the standard long explanations." I was intrigued. Every couple of years, i get one of these students who actually enjoys studying chemistry specifically. Probing deeper, i asked, "Why Chemistry? How about Math? Or Bio?" "Math is not as straightforward as before, Bio is a LOT of memory work. Chemistry is more straightforward, i enjoy doing organic chem questions" "When did you start to like studying Chemistry?" "I used to fail Chemistry, until i attended Jeremy's tuition lessons. (Jeremy's my partner for O level Chemistry) He taught me how ...

Online Tuition – The Next Paradigm Shift
Online Tuition Online Tuition, the next major paradigm shift. Every tuition, whether private or centre, has to adapt to this new paradigm. Even the students. Every student or parent or centre or teacher who does not embrace this shift will be left behind. People who cling on to the old ways of giving tuition will be left behind. Now i got to give a disclaimer, i'm no prophet. Tried giving online lessons 2 years ago but students were not keen. So i dropped the idea. Now this idea is forcibly pushed upon us so nobody has a choice. Students who think they are very smart and simply login, mark their attendance (for school lessons) and then go to bed will ...

Hydridization
Hybridization It is one of the most mysterious concept to the JC chemistry students. This is a concept that is mainly for carbon atom. Some colleges teach it under chemical bonding, others teach it during introduction to organic chemistry. No matter where it's taught, it would be good if you understand what is the main idea here. Main Gist Hybridization is simply mixing of atomic orbitals, notably the s and p orbitals for carbon. 1 s + 1 p = two sp hybrid orbitals     => shape: linear (180 bond angle) 1 s + 2 p = three sp^2 hybrid orbitals   => shape: trigonal planar (120 bond angle) 1 s + 3 p = four sp^3 hybrid orbitals   => ...
