Just 2 months of IIT are left. Please tell me how to best utilize this time and obtain a good rank. [MY FUNDAMENTALS ARE CLEAR AND SOLVE PREVIOUS YEAR QUESTIONS OF MOST CHANPTERS WITH EASE. WEAKNESS: CALCULUS CTRENGTH : ENTIRE PHYSICS]
Revise as much as possible. Revision is a very key factor to get a good rank.
Apart from that work on your weak areas as well. Calculus is an important topic of Maths.
And from Physics poinf of view, Mechanics, Electricity, and Magnetism are key topics. Read them and clear your basics. You can crack IIT JEE easily once your fundamentals are clear.
Wish you all the best for JEE-12.
