Don't  drop at  all
Work hard for 10 years & keep iitans as your labours

Hi Vivek Patil!!

Actually you can get admission because sometimes it is not necessary to get above 75% and it is enough to get above 65% sometimes. So I think you can get admission. Don't waste your entire year for that

Choice is yours

ALL THE BEST!!!

Hey Vivek,
To get admission in NIT/IIT, you have to score either 75% or be in the top 20 percentile in your class 12tg board exams in the year itself in which you have given the exams. So, if you were in the top 20 percentile this year, and if you take drop, then you need not to give 12th exam again.
I hope this helps!
