B.A

If you are looking for careers in the corporate as of now, BBA is better. If you are looking for evolving yourself more, choosing the subject which you like most then BA liberal arts is better. If you see the content of BA liberal arts the range of courses offered at SSLA is expansive. From anthropology, archaeology, film studies to usual subjects like maths, computer science, business studies, etc. So don't be surprised if you come across a Philosophy major who is rushing through the corridors to attend his or her Women and Gender studies class.
To this, add compulsory courses dealing in logic, finance, history, etc. and elective subjects such as Marketing, Marxism, Urban Sociology, Global Warming, Ballroom Dancing and what not. That means you can define your combination and choose the course which you may like unlike well-structured BBA program. BBA will give you a better placement opportunity now and BA liberal arts may make you a better manager and a better human being.

You have pretty good marks in class 11th. I wonder why you want to change the stream.
Unless you have strong interest in political Science, I would recommend you to continue with commerce field.
As for the calculation of best four subjects:
For BA
1. One language, which can be core subject, or elective, or functional
2. The subject that you're applying for. If you don't choose that subject as part of your best of four, you might be at a disadvantage of about 2%
3. Two other subjects from List A (List A includes disciples that are offered by the varsity for admission to its undergraduate programs.)
For B.Com:
1. One language, either core subject, or elective, or functional
2. Should have passed commerce/accountancy
3. Two other subjects from List A

Hi Lovepreet,
I have already answered a similar question for you.
BA in mass communication does not have any subject related to political science but a person having knowledge of political science will surely have an edge over other candidates pursuing the same program. If you aspire to become a journalism, especially a news reporter, anchor, or of any other profile in the print of TV industry, you knowledge of political science keeps you a step ahead of people fitting in the same profile. You will get to learn and read a lot of news papers, see television to understand the current political situations of the country and the world and with that, you can strengthen your knowledge of political science. I hope, it is clear.
All the best.
