See for aiims you need to work really very hard because aiims don't directly asks questions from ncert , so you need to refer other good books as well for aiims. There are plenty of good books in the market but that won't help you if you are not solving MCQ's. Solving MCQ's gives you advantage to solve questions on time and more accurately . Your mind works faster if you solve MCQ's. Try solving previous year's question papers of aiims and that will help you to develop skills to solve questions on time.
I hope this was helpful to you and for any more further questions please feel free to ask anytime.
