Hello,

For admissions in NITs and IITs  candidates should have passed class 12th with a minimum of 75% marks or they must be in the top 20 percentile in their class 12 examination and 65% for SC/ST candidates. So you won't be eligible for admissions in NITs and IITs. You will be able to give JEE main but you will not get admissions in NITs, IITs or GFITs. Candidates should have passed class 12 or qualifying the exam in 2019 or 2020 are eligible to give JEE main.

You haven't mentioned your Category. Nevertheless. to qualify for JEE Mains, there is no minimum aggregate criteria. But if you want to join NITs, IIITs or CFTIs then you should score a minimum aggregate of 75% only in your 12th. 11th marks aren't considered. And then to appear for JEE Advanced which is the gateway for admission to IITs, you will need to fulfill the 75% aggregate condition. Now it is 75% for General Category and 65% for Reserved Categories. So how much you score in 12th is what matters to secure your eligibility for NITs, IIITs, CFTIs and JEE Advanced. With 63% you do qualify for JEE Mains but cannot take admission in NITs, IIITs or CFTIs and also you do not qualify for JEE Advanced for admission to IITs as the required percentage is 65% for SC/ST and 75% for General Category, OBC, EWS.
