Dear Rachana, the ideal eligibility criteria for a Candidate to apply for AIIMS, JIPMER and PGI or for that matter any PG course is that you should have completed your MBBS along with 1 year rotatory mandatory internship and with n aggregate required for your Category. The rules do not mention anywhere that a Candidate should have completed his course in the meant period or shouldn't have had backlogs while studying. So even if you have passed 6 months later than the course time, if you have scored the minimum aggregate against your Category in MBBS and have completed your 1 year internship or will complete it by the mentioned period, you are eligible for these examinations.
