B.Com

Hi,
It is a good course. After completing B.Com, you can do many courses and get a good job. You can BBA+ MBA, B.Com+ MBA, CA, CS and other certified courses.
Nothing is bad, you just find the course which fits your area of interest.

Yes, you can, but through distance learning, you cannot get PGDM, it will be PGCM. I wish you all the best.

You do your PG in that subject where you have scored the highest marks. After PG, you can go for assistant lecturer job in a government college by clearing NET or SLET. You can appear for UPSC exam or can go for research work.
Many options are available for trade and commerce.

1. Infrastructure: Both are at par
2. Rankings: NMIMS
