Hey Aishwarya, You will be scoring 310 marks in NEET 2019 and you also belong from OBC. Really that will be very helpful to you while taking admission in Government Colleges as some special seats are being reserved for each and every special reserved category. With these marks, you can get a seat in medical government college but you might be getting difficulty for that. you belong to Karnataka and at even 450 from the general category can take a seat easily in Government college but due to high cutoffs this year nothing could be said about this. Last time students have got the seat but in the last rounds and with very difficulties. I would say that you should first wait for the result and then you can check your marks and then see the college website. First, you can see the government college in your state as you will get a seat under home state quota too. I would personally like to suggest you to check for colleges in your state as you will get a seat under reserved quota and even you can check at NEET PREDICTOR.

Dear Sir / Ma'm, the least cut-off for a government medical college in Karnataka was 338 for the Raichur Institute of Medical Sciences, Raichur. So, you should better focus on the private colleges of your state where you might as well have chances for admission. However, these cut-offs are always subject to change.
