Hello,

To be eligible to get admission in IITs/NITs/GFTIs a candidate must have passed 10+2 with atleast 75% for general category and for SC/ST it is 65%.Now for admission in B.E/B.tech Physics and Mathematics are compulsory subjects along with Chemistry/Biology/Biotechnology/Technical Vocational Subject.So you cannot exclude Maths.And you need to score 75% aggregate overall not in each individual subject.
