Hey Neeraj

You need to mention your domicile state. In some states like West Bengal the cutoff for SC category is low (around 280 if one sticks to the last rounds of counselling) whereas in some states it really high as in Rajasthan.

From a broader point of view, with 310 in NEET and SC quota reservation it is highly possible that you can get a government medical college (the fees not being more than 10,000 (however it varies depending on the college you get).

To check your chances of getting a college in NEET you can use https://medicine.careers360.com/neet-college-predictor and then you can check the fees of that college.

All the best!
