Hi ,

I dont think any topic is more important than others . I would suggest you to start studying hard aand cover as many topics as possible . Be sure to cover main topics like

1. Mathematics - calculus, complex , co-ordinate,sequence and series

2.Physics - Conservation of energy and momentum , electrostat , and waves

3. chemistry - organic (mechanisms ) , physical chemistry , and periodic table , solid state
