Colleges in Ahmedabad

Your 12th mark will serve as a huge hindrance for a call from IIM A. I suggest you to try for colleges which are more lenient in terms of acads: MDI/FMS etc.

Yes, in fact the incoming programme PGP has around 5% CAs at IIM-A.

IIM A does not offer BBA. You can pursue your Bachelors degree in the field you are interested in. Speaking about MBA/PGDM, as a fresher, you can either opt for PGDM from any of the IIMs or you can opt for MIM ( Masters in Management) from any college abroad, all are equally good provided you are not looking fro placements. Indian colleges provide placement to students, but such is not the case of foreign institutes. Please find the FT world ranking for MIM: http://rankings.ft.com/businessschoolrankings/masters-in-management-2016

Yes, you can. If not explicitly, then implicitly. It is all about demand and supply.

HL College of Commerce is the best option for you to pursue B.Com.

Yes, exams are conducted on time. The average salary is around 4.2 LPA and mostly sales profile is given. For Finance and HR, do not expect much. But BK is far better than rest of the other colleges in Gujarat except IIM, Nirma and MICA, but you need CAT for that.

Sorry, I have no idea about Shanti Business School, so cannot answer your question. You also need to specify on what basis do you want to compare the institutes.
