You have to give entrance exam of the university i.e.,VITEEE.

Chances are there to get MNIT for CSE with this JEE score.

Hi Rahul, Candidates must have completed 10+2 with Physics, Chemistry, and Mathematics (PCM) from a recognised board or institution to opt for B.Tech. Computer Science course. Every college is different and their admission process varies accordingly. Some universities may accept maths as an additional subject it is advisable to get in touch with the college officials for detailed information. https://www.shiksha.com/b-tech/exams/jee-main
Thanks.

Hello Gunja,
Astrophysics! It's a greatly fascinating subject provided you have some interest in it. It's basically an observational science rather than an experimental one. Yes, engineering graduates can start in this field. I am attaching a link that will give you all the required information.
