B.Sc

Depends on your interest. But B.Sc nursing has large scope. It has many vacancies every year. And, nursing is a well paid job.

Yes, you can apply as a perusing candidate, but you have to score above 50% in final for admission.

You can opt for MS programme and look up in which field you are good.

I definitely suggest you to go with B.Sc. And in the mean while you Can focus on the history part which you have studied in the high school level. Read NCERT text from 8 to 10th regularly in case of history and geography.

Hi Rakhi,
Every college/university has its own eligibility criteria. Please confirm the college in which you want to pursue the course or you can also check the same on the college website for more detailed information. Regards.

You can go for MCA or M.Sc in CS/IT. You can think for MBA too after cracking management entrance test. If you like teaching profession, go for B.Ed.
Best wishes.

Yes sure, you need to fill online form, and you also sit for a Entrance Exam & P.I.
