Dear Anjali,

Yes, B.A (hons) in Economics is a part of Bachelor in Arts .Well, it would be better if you had economics as a subject in 12th .Some colleges also offers B.sc in Economics , for that case ,you should have mathematics in your 12th class (science stream is preferable).

Here you can find the college lists that offers B.A hons in Economics :
