You can pursue B.Com after class 12th. Many colleges offer admission to the course on the basis of marks obtained by students in class 12th. Colleges in University of Delhi offer admission based on the cut off released by the colleges.

No, don't go for repeating the exam. You can continue with it, and try to achieve good percentage in your last year of B.Com. And, for getting admission in IIMS, start preparing for CAT right now and score well in the CAT exam. They will definitely get you top B school or IIMS. Also, do some preparation for GD and PI process.

4 PM to 7 PM. There is leniency in attendance. Some of my friends study here.

Hello for your question I mention a site for you hope this will help you

No doubt, Bhartu Vidyapeeth is better than MLSU. Go for that to pursue B.Com. BVP Pune is really a good university in all aspects like infrastructure, study, placements etc. Hope this helps you.
Thanks.

Depends if that ECA is in DCAC or not
Given the trials and clearing it you can opt for any college that has ECA you are looking for.
