Hello Abhishek, I can understand your angst and worries but what happened? Why are you not able to complete your Diploma? No issues. Based on your 12th marks you can take admission in any degree course of arts or commerce or science. Best wishes.

No, you will not be eligible for M.com.
Because you need to complete your graduation in B.com.
Only a B.com student can apply For M.com.

He can do some certification course in the duration till he clears his backlog. It is not worth to drop the course for anything else. So do 1-year Diploma or certification course in the field he is interested in.

Possibly in March next year. That will be March 2019.

Maybe, you can get the course in the 2nd round of counselling depending upon the university criteria.

In my opinion Panjab University is the best among the two as Punjab University offers some of it's student to go abroad for their fieldwork which is not given by other universities.

No, right now, you cannot get admission in PU as the last date to apply for the admissions has passed.
