Hello Satya,

The NEET cut off varies from year to year, state to state and as well as college to college. It also depends on the Quota you are applying through as well as the Category of Admission. Government and Private Colleges have cut-offs of their own.

Assuming you are applying through the 15% All India Quota under Scheduled Caste Category for a Government Medical College, the cut-off for NEET 2017 was Rank 38,668 which corresponds to a score of approximately 440 marks out of 720.

This year, as competition gets tougher every year, you must get a score above 480 to ensure a seat in a good Government Medical College.
All the very best!
