you only will have to appear for the subject you have less marks in. You can take admission.

yes he or she can do again m.com again in any of the subject he or she wanted to go. he or she can will be elligible for the same. all the best have a great future ahead.

No once you have done your masters degree you can't do it again until n unless you failed or dropped out due to some reasons but if you have passed your PG and have you degree you can't do it again as it is meaningless but if you want to study more about your subject then you can go for PHD. in that.
Good Luck.
