Accounting

Yes there is a university level entrance exam there for admission into B.Com accounting and finance. Rest you can call their admissions cell to confirm about the same.

Except CSE, you can get all the branches in the above-mentioned colleges. You can get CSE in the 4th or 5th round.

I would rather suggest you to go for IIT first and do not lose your 1 year in B.Tech. If you don't have the option right now then you should study and prepare for the entrance exam of IIT then if pass then further procedure will start.

Dear,
A student, who has completed +2 with Science having Mathematics as a compulsory subject and has covered it sincerely, can smoothly handle BBA in Maths & Accounts.
Best wishes.

Yes, in the first year you need to study accounting as a subject. It is compulsory.

Certification course on internal audit is always an edge over other, if you are looking for such profile. Moreover, if you take degree from IIA (Institute of internal auditor), you can easily fetch good job in IT based company like Infy, TCS and wirpo etc.

It's all on your interests. According to your marks, you can easily pursue B.Tech in IPU. But, if you have full faith that you can crack the next year IIT entrance exams, then only go for one year drop. Otherwise, if you have doubt then do not take a risk of one year. My suggestion is don't go for one year drop, pursue B.Tech in USIT, and then score good in college. All the very best.

B.Tech has higher value than B.Sc. But. As u say B.Tech has only better value if u finishes it from a better college. So in my viewpoint finish B.Sc. CS from S. R. M and then do a master degree. This will fetch u with good salary package. Good luck!
