hi,

see if you have final pass marksheet and certificate of b.com (//b.com) pass , then you are eligible to apply for relevant jobs application. convocation is usually late for many of the university, some times after declaring results, after 1-2 month , convocation taken place. in case you do not have the provisional certificate, you may take a xerox or photo copy of online certificate and duly signed by the head of the institute. this certificate would work until you receive your original provisional certificate.

hope you understand.
