Hi

To be eligible for  CFTIs, NITs, IIITs, GFTIs , IITs one needs at least  75% marks in aggregate in class 12 if belong to general or obc category or at least  65% marks if belongs to SC/ST or  must be in the top 20 percentile in  class 12 examination.

5 Subjects to be considered for calculating aggregate percentage are :-

*Physics

*Chemistry

*Mathematics

*A language

*Any subject other than listed above

So, if you are from general category you need at least 75% in above aggregate of 5 subjects and not only in aggregate of physics chemistry and mathematics.

Thank you
