Science

Polytechnic is not a degree. It's a diploma. You can do degree after diploma.

Hi Kshitij,
You can do BE or B.Tech after polytechnic. Then, after your degree, you can do ME, M.Tech or MBA.

Hello, yes you are eligible for M.Sc in physics.

Hello Shubhra,
Yes, you are eligible for CSIR NET exam. As you have done M.Sc in biotechnology, you can appear for CSIR NET Chemical Sciences or Life Sciences. If you want to go for JRF exam, then make sure that your age is not more than 28 years and you should have minimum 55% aggregate marks. Or if you want to apply for the position of an assistant professor, you can apply anytime as there is no upper age limit. But you have to fulfil the educational requirement.

Hello there,
Physics and chemistry are the compulsory subjects in HSC. In the elective courses, you can either choose maths or biology.
Regards.
