Best JC/IP Chemistry Tuition

Skyrocket Your Chem Grades with Ex-RJC Lecturer Mr Donnell Koh and Singapore’s Most Popular Chemistry Tuition Since 2008!

– Students can choose either to attend physical or livestream lessons. However due to social distancing measures, physical classroom lessons are currently capped at max of 15 per class.

– Lessons are taught from scratch so to ensure every single student have the foundation that is needed to understand each topic holistically and thoroughly. We leave no stones unturned. Lessons are carried out first by going through the concepts followed by problem solving. This allows students to see and understand how the concepts are linked to commonly tested prelim and A level questions. The questions are carefully curated by the teachers with their vast experience in the subject.

– Junior College education is merely a short 2 years and the learning pace is very intense. Students who struggle with Chemistry should start early as once they fallbehind, they will find it very difficult to catch up. So the advice is to seek help early and do not leave it to the last minute. Our experience is that students who start with Twig early enjoy Chemistry more and have less problem doing their tutorials/exams and do well for the final A level exams.

– A Level Chemistry is a content heavy and rule-based subject. There are a lot of rules to follow and it is a huge jump from O Level Chemistry. Let’s see the differences between the different A Level Chemistry levels.
