how many marks should i get in b.com

you should at least get 50% marks to get admision in master degree , today this is minimum percentage by AICTE or UGC to get admission in Most of Master degree

If you want to do masters in top colleges, then you need to get above 95%.

Hi, I would request you to be a bit more specific and mention the educational background, name of the course you are interested in, location, interest areas etc as such information will help me to provide you right guidance. Waiting for the revert. All the Best!
