I taught two sec2 students in maths before.Currently I'm teaching two pri kids in chinese and one in maths and two sec students in maths.For my students,I will first find out their weakness and then focus on training them on their weaker parts.Problem solving skill is very important in dealing with questions and thus I think the simpliest way to do any question is to simplify it.In other words,knowing what the question is asking for and knowing it clearly.Other than skill,frequent practice is needed.To me,practice makes perfect.This is very true because I used to fail Chemistry in my JC2 Common Test.But as I changed my studying method and kept practicing,I became the MOST IMPROVED student in prelim and I got As in both prelim and A-level.
