And yes its for all subjects and nothing like best of 5 or such type.

hi aritra,

            If you want to qualify the jee mains exam then For admissions to NITs/ IIITs/ GFTIs, candidates should have secured at least 75% marks in class 12th exam or be in the top 20 percentile in the class 12th exam conducted by the respective board. For SC/ ST candidates, the eligibility criteria is 65% marks in class XII.

Hope this helped you.

Best of luck.
