Science

Yes Mahima, it is a good option for you to pursue a B.Sc course.

Hi Nilabh,
Admission procedure is goes like this:
Do check whether you are eligible or not.
If yes, then you have to fill up the online application form, print the needful and pay the fees.
Wait for the list to be declared. If you find your name on the list, then rest instructions will be there.
But, unfortunately you can do all the above mentioned in the next year, because the application is over and the list is out too.
Anyway, All the best.

Yes, you can if you have a good or medium score in CET (if you are from that state) or else you should have a good ranking in JRF then only you can get a seat.

Without physics, it's impossible. You have to calculate force at different angle at every stage. If you don't love physics, civil engineering will be quite tough for you.

Preparing for GATE is a good option. It all depends on your interest whether you are willing to pursue BE or B.Sc.

Hello Amrut,
If you have not taken biology in class 12th, the doors of the medical stream are closed for you. You can think of some other profession. What is your passion other than medical? Try to take this line for your graduation.
