The normal eligibility criteria for B.Sc. Math Hons degree course is a pass degree in 10+2 or equivalent examination in Science stream with at least 50% marks obtained by candidates in Mathematics subject or in aggregate from a recognised board or Institute. Therefore, arts stream students of 12th cannot do B.Sc. Mathematics (Hons).

No, it's not compulsory. As per JEE Mains eligibility criteria, candidates should have obtained a minimum of 75% marks in class 12 or equivalent exam or they must be in the top 20 percentile in their class 12th examination. For SC/ ST, the eligibility is to obtain a minimum of 65% marks in class 12 or equivalent. Therefore, it is not necessary to obtain 75% marks in PCM in 12th.

Eligibility criteria: 10+2 with a combination of Physics, Chemistry and Maths or Computer science or equivalent as one of the subjects with 50% marks (45% for SC/ST/PH) from recognized Board/University.

B.Tech has advantages over B.Sc in terms of job opportunities. B.Tech degree holders have several employment options like GATE PSUs, UPSC, UPSC-IES, AFCAT ISRO, DRDO, CDS Railways, Banks and Private sectors. B.Tech degree holders of IITs, NITs and IIITs have the best campus placement opportunities and most of them have two or more employment options before the completion of their B.Tech degree. Therefore, B.Tech is much better.
