I am a 2nd year student . I want to change my college and start from 3rd year in MMC chennai
See the transfer of Medical Colleges can be done on the availability of the vacant seat in the college you want to opt for. I would recommend you to contact your college and get it discussed, they will guide you out regarding the procedure. The transfers are very few so the possibility of getting a seat in any other college is feeble but still you can try for it.

I hope this answer helps. All the very best for your future endeavors!
