B.Com

Talking about career and job prospects in India after B.Com (Hons), it isn't having much of opportunities as there is so much of competition out there. So yes, it can be said that B.Com (Hons) is not enough for good career building. The exception is that you studied from SRCC or Hansraj that can get you placed with a package of 10 LPA or so.
Hence, it is advisable to go for post graduation or some professional qualification in order to build a career.
Talking about the job prospects abroad, it carries hardly any opportunities out there.
See, I agree that skills do matter but in order to show skills, it is essential to get a job or get an interview call which isn't easy with B.Com (Hons) degree nowadays as there are so many others with BBA and Master's degrees. And yes, companies prefer management graduates over normal graduates.

Hi,
Institute of Computer Accountants (ICA), Jaipur was founded in the year 1999 by a group of professionals with considerable work experience in the field of accounts and taxation. ICA family includes more than 3000+competent staff members and more than 2,00,000 students and is known as India's No.1 institute in Accounts and Banking (Finance and Taxation). The Institute spreads to more than 450+centres with 3 zonal offices and 50+ placement offices across India with head office at Kolkata.
IIBMS doesn't offer B.Com, but it offers BBA. So, there cannot be any comparison between the two. However, IIBMS is not a fake institute but it is an autonomous institute which is not recognised by any educational body. It is an associate partner of various recognized universities in India like PTU, Vinayak's Mission University, etc. So, if you do a degree program from this institute, you will get two certificates for those degree programmes for which it has associations with other universities.

First of all, you need to understand the difference between BBA and B.Com and then select a course accordingly.
Delhi University
Pros: Brand name, good academics, good Fests and societies. No attendance issues.
Cons: Bottom colleges are decent in terms of academics and placements.
Maharaja Surajmal Institute
Pros: Reputation, discipline, great academics and good placements.
Cons: Attendance issues.
To sum it up, if you're planning to pursue CA/CS/IAS, etc., along with your graduation then I would recommend Delhi University as it has less attendance issues plus shorter duration of classes.
Otherwise, if you have no such intention or you get a bottom college of Delhi University you may consider Maharaja Surajmal Institute as it's an equally reputed college with good academics.
All the best.
