I got 81% in cbse 12th board last year & currently preparing for iit. I want to give improvement exam. Should I go for it ?
To get admission in IITs, NITs & GFTIs you should have minimum 75% or you should be in top 20 percentile in class 12th. So you don't need to give improvement exam. To check the further eligibility you can go through with given below link.
Good Luck!
