Math doesn't matters whether you have taken it or not in your 12th grade. B.Com has nothing to do with it. Some colleges prefer math at the time of taking admission. You can cross check first what this college wants?

For BBA and B.Com, it is very simple, they have a mass recruitment and campus placements for high academy toppers, but salary packages are not so good. It is around INR. 1 Lacs to INR. 2 Lacs per annum. So, I will recommend you will choose better University than Punjab University for BBA and B.Com, if you want to get a good job.

After completion of your Bachelor's degree, you would be eligible to take admission in MBA College.

No, its not compulsory, they runs variour programs in various fiels so, you can choose one of them.

You are definitely eligible for applying for B.Ed after completing B.Com and MCA course. For B.Ed, the minimum requirement is that you must be graduate. It does not matter from which course and which stream, and it will give you benefit of doing MCA. So, you need not to worry and can definitely apply.
