Accounting & Commerce

There is nothing as minimum marks. You give entrance exam like everyone else, then the names get shortlisted depending on the number of seats. Let's say B.A. Economics has 60 seats. Then, the first 60 rankers will get it (including quota). So, no one can predict what would be the least score which converts the seat.

It's going to be tough. You can try somewhere else or apply next year.

No special course is required for admission in foreign universities. Just those basic eligibility criteria, like every other Indian college. For admission, you will have to give an entrance exam for the desired course conducted by that very university, you wish to go in.

You will have to first complete your graduation with more than 50% marks. Only post it, can you purse MBA as MBA is a Masters program. If you find it difficult to complete B.Com then you can try your BA as an external student and complete it via correspondence in 2 years' time.

Since you are giving us options to choose between B.Com (Hons) or BBA so I'm assuming that you are interested in both of the courses equally. Look, Delhi University is well reputed, recognised and everyone gives first priority to DU then comes IP University. ARSD of DU is one of the reputed colleges which is perfect in every aspect.

Yes, there are chances as this year colleges are out with most realist cutoffs. Look for other colleges' cutoff also.
