I am from assam board AHSEC, my subjects are English, chemistry, maths, physics, biology and alternative english.
For admissions toNITs/IIITs/GFTIs:
Candidates need to have secured a minimum 75% marks in class XII or equivalent exam or be in the top 20 percentile in their class XII exam conducted by the respective board.
For SC/ ST candidates, the eligibility criteria are to secure 65% marks in class XII or equivalent exam.
All subjects marks are carried in admission criteria.
You can get admission in private institutions if your overall percentage is less than 75.
But if your aggregate percentage is above 75 than you can fetch seat in NIT,GFTI,CFTIs based upon your jee main percentile.
There are different rule for home state quota and state entrance exam.
