I've finished BBA, can I do M.Com?

Yes you can. But I would suggest doing MBA instead. You can apply for M.Com. at your nearest college for admission for ease. If you want to pursue the course from a prestigious university then you will have to apply for entrance exam. Or you can do M.Com through Correspondence.

Well, you can do M.Com if you have completed UG with 50% aggregate marks in Bachelor's degree (Commerce or Management or Economics or Accounts) or equivalent. But again try to check other potential courses also. Lovely Professional University, Sri Ram College of Commerce, Manav Rachna University, et

Yes, you can go for M.Com after your BBA, but I will suggest you to go for MBA, which gives you more benefits than M.Com. Go for MBA finance, if you are interested in financial field.

Yes you can, but it will be more beneficial to you if you do MBA.

Yes, you can pursue M.Com after BBA. After BBA, you can pursue a lot many course out of which M.Com is an option. But, it would be better, if you do MBA. Good luck.
