How to Crack the Paper
I think I can be one of the best persons in answering this question, I would request everyone to attend the lectures and the materials offered by the professors, during my tenure at IIT KGP, this course was taught by Prof. O P Sha & Prof. V Nagarajan (Two best professors in the Dept.).
Ensure to understand the theoretical concepts and practice examples over the same.
