I am trying hard for aiims delhi
ncert is sufficient for neet ,condition being you should know each and every line thoroughly and also you should go deep by its meaning..... for aiims ncert is important as the most tricky questions are actually the most hidden lines of ncert.... you should go through previous years question papers of aiims. you will see that more than 75% questions are from ncert but for other two subjects theory is from ncert and you must have a very good practice of questions solving.... go through the papers and see what will be best for you.....
