Accounting & Commerce

B.com and BBA are good options but you should choose the major according to your interest.
If you are interested to continue your study abroad, there are many programs available for you but for this, you have to prove your level of English by taking an IELTS or a TOEFL exam.

Definitely, you can. The previous performance isn't considered to judge you but you need to work hard to get a better result even if it is CMA, ACCA, CA, CS, or anything, you can do it.

To complete your studies from Canada, you can go for online class like CMA (US), which can be completed within short period of time itself because than MBA, CMA (US) has more scope. For MBA, the fee is Rs.5 lakhs to Rs.6 lakhs, but for CMA it is lesser.

After B.Com, you can prefer some professional course like CMA (US), which is related to finance, so you can get more knowledge and it can be completed within 8 months to 1 year and it has better scope all over the world.

Dear ,
Yes you can plan for actuarial science with PCM or even commerce stream because math subject has important role in this field, specially stats part.
But for the good opportunities you should have good command over math subject.
Even you can do B.Sc maths (Hons.) and than plan for Actuarial Science exam that will be good combination in terms of strong foundation of math subject.
All the best

Yes, you can change your university in the 2nd year, but here comes a condition that the college in which you want to go allows lateral admission or not and some colleges and universities have some prior benchmarks that you need to achieve before taking lateral admission. I would refer that, first check it with the university that they allow lateral admissions or not and what all are their benchmarks.

Yes, this is a good option as many people are not able to cope up with both of the courses. It becomes slightly difficult to attend classes of both at the same time. In CA, you will cover every bit of financial sector and that would help you in near future while giving the final exams.

You can apply to the following universities:
WCU in USA
Brunel University, London
Keele University, UK
Ball State University, USA
