Hello,

For any exam,there is some prescribed books and reference books. You can get the list with syllabus. for IIT, the most prescribed books are NCERT books. after that other reference books are considered for solving questions and getting the question bank.

To get a seat in any college you have to score an eligible or satisfying rank to the cutoff rank range of that respective college. To get good score you have to study with a high potential and perform in your best way. To perform best, you have to practice best which will take your time, your hardwork and smart work. There is a long process and take time to excel it.

Hope it helps!
