Hello aspirant

With 220 marks in NEET UG exam, you will not be able to fetch a seat in any government college or private medical college. An OBC candidate requires atleast 585+ marks according to NEET 2021 cut off marks.

You only have chances of getting a few deemed medical colleges which are listed below-

Sree Balaji Medical College, Chennai- 130

Chettinad Medical College, Kancheepuram- 159

Santosh Medical College, Ghaziabad- 181

Vinayaka Missions Medical College, Karaikal-

Sri Lakshmi Narayan medical college, Pondicherry- 108

Please note that the cut off changes every year depending on various factors such as category of the student, number of students attempting the exam, difficulty level of the exam etc
