Hello Aspirant,

Yes of course you can do so. If you are seeking admission in any of the NITs/DTU/NSIT for their B.Tech course then first of all you have to appear for JEE-Main and kindly note that if you have appeared again for class 12th as regular candidate then your passing result will be considered but if you have repeated your class 12th as a private candidate then your passing year will be considered as of first attempt and according to it your attempts for JEE-Main will be considered. For JEE-Main 2021 the candidate should have passed class 12th in 2019 or later or the candidates appearing for their class 12th in this year are eligible to appear in JEE-Main 2021. This is because maximum number of attempt allowed for JEE-Main are 3 for three consecutive years which includes the passing year of class 12th.

There was percentage criteria to be eligible for admission to NITs/IIITs/CFTIs but due to the pandemic COVID-19 it has been waived off from this year so if you are only pass in your all subjects of class 12th then also you can go for NITs/IIITs/CFTIs or for JEE-Advance if you qualify JEE-Main.

This year JEE-Main is being conducted with slight changes in it's pattern and it's conduction and you can check out all the changes from the link given below :-
