Dear Dolma, if you are enquiring about Medical colleges, your 10+2 marks are only needed for procuring eligibility to appear for NEET, JIPMER and AIIMS which are the only Medical entrance examinations in India. After that what gets you a medical seat is how performed in NEET and your Category. This applies even to Dental, Ayush and Veterinary courses. However, if you are talking about other courses like Physiotherapy, Occupational Therapy, etc it depends on where you want to join and their respective admission processes.
