hello aspirant,

Although giving about half an hour for revisions in each subjects - Physics, chemistry and Mathematics is not bad, but you must try to give at least 2 hours of minimum time for revising each and every subject thoroughly. I will not talk about how much time every toppers give into revising each concept and subjects thoroughly as every student is different from others and has different level of understanding and soaking up the concepts. So, you must try to take out some more time, as much as you can, and you must devote that quality time to your studies and preparation for IIT JEE. This is important because IIT JEE is one of the toughest Exam in India and in order to secure a certified position or rank in this exam, you have to beat yourself as well as millions of other competitors as well who are preparing for this exam along with you.
