read through and understand the theories i guess
for chemistry and physics it is important to know how to apply the
formulas and theories and whatever laws. for chemistry right imo
chemical calculations, qa and organic chem are the hardest. for
physics, mechanics can be quick tricky so just practice practice
and practise. try more types of questions
for bio right, i think its a lot of memorising and regurgitating
according to the requirements of the questions. oh yes must
remember the food tests for practicals!
