Biology; Chemistry; Physics: Post your doubts here!

[♫Prince Shah♫]

for Chemistry, the past papers are available on xpc and u can solve them
what i did was solve the MCQs first, then the theory and then the ATP
what u shud do is the same
first solve all the MCQ papers, as many novel concepts are there that can help ur theory
after solving all the MCQ papers solve ATP, as the questions there are simple and u will have further practice
then solve the theory
