I have ESI quota and I am from OBC and my AIR is 65000.will I get in Coimbatore govt medical college.

You can apply for its counselling only after the final decision of high court on esic colleges case.  So wait for the decision.

And last year the opening marks for  mbbs in esic coimbatore for general category were 558.

Just stay aware and updated.

For any other information you can ask us. Neverthless, you havent mentioned your Category. In 2018 under State Quota, the cut offs for ESIC Coimbatore College have been as follows:

General Category:  558
OBC: 555
SC: 421
ST: 403
With 480 marks unless you belong to SC/ST Category, it is difficult.

The cutoffs might even increase higher this year since the number of candidates had increased and also the paper level was called easy comparatively.

Thankyou.
