B.A

Hi Yusuf,
According to Indian education act-1959 you cannot pursue two degrees simultaneously, because it causes extra burden on students (according to law makers). But after the recommendation of few universities UGC has now granted the permission for students to get enrolled in two degrees (in same or different universities). But this law has been changed since 2013 permitting its full-n-functional use from 2014-2015 academic years. So interested students can enroll in two degrees simultaneously whether from the same university or the different. Though there can still be a few hidden points where courses to be chosen might have a rule for forming the pair of courses a student can apply for about which I have no knowledge. In fact, it is always appreciated as you will be considered to be someone who wishes to keep learning and growing in your career. Good luck.

Yes, you can surely do BA after completing 10+2 with Science or commerce stream.
There are a lot of subjects which are related to commerce like- economics, etc. And Science like- psychology, statistics etc. And many other subjects which are really very useful for job and society
BT if talk about society and the stereotype of public about BA
They thinks if anybody is pursuing B.A. He/she will study the subject like philosophy, home Science and literature etc. They thinks that a Student of B.A. Is practically useless
I want this stereotype must change. Because lot of students pursuing BA feel embarrassing when their relatives asked about their studies. Lot of students who are interested in such subjects but due to social reasons, their parents send them to study science.
