B.A Sociology

There are some chances to get admission in Banasthanli, so you can apply for admission.
Good luck.

There is no entrance exam but through 12 result class.
Ba in sociology is good in Banasthali Vidyapeeth as there are extra curriculum activities you can participate in.
Panchmukhi shishka.

If you were a Science student in your intermediate, you can certainly apply for B.Sc. Degrees can't be interchanged.

According to me, B.Com is best especially if you have basic knowledge taught in class 11th and 12th. Otherwise, you can go for other option. B.Com is best as it may create a pool of job opportunities like accountant, marketing etc. And, this will also help in doing any course like CA etc.

Minimum eligibility criterion is 60%.and no seat status is out till now on any official site of banasthali vidyapeeth till now.
so , you can also refer to banasthali.org for more concerned doubts.

Royal Global University is the only university in Guwahati which offers B.A. (Hons) in Sociology.
