Hi there.

In India, only 3 entrance examinations are held for the course of MBBS across the country. The examinations being, 1. NEET-UG 2. AIIMS MBBS 3. JIPMER

The first examination's result is valid for taking admissions in all medical courses like MBBS, BDS, BAMS, etc. in all government and private medical institutions of India except AIIMS and JIPMER.

AIIMS and JIPMER are two premier leading medical colleges of India (there are more than 5 AIIMS colleges in our country, the leading one being in Delhi) which held their own entrance examination for providing admissions in MBBS courses.

COMEDK doesn't occurs for admission into MBBS courses.

Here's the link of all the above mentioned 3 examinations :
