Science

After completing B.Sc in Geology, you can apply for coal mining or other such mining companies. You can also apply for various government exams like MPSC, UPSC, and SSC etc.

You would be eligible for the course if you have studied Physics, Mathematics, Biology in 10+2. Selection is based on the merit list.

Yes, physics is important for B.Sc. But you can leave it after that if you wishing to pursue Masters.

Hi,
You have a great percentage. Choose only those field in which your are interested in, and wants to build your career in it. Prefer those stream which would be easy & interesting for you. If you want u can opt engineering, medical (if bio), else if interested in civil services, or apart from this,

Hey there,
Yes, you definitely can. In fact, I can personally vouch for it because even I was a science student but later opted out of it to pursue a BBA. You can manage it without any problems.
Good luck!
