It's quite difficult. The cutoffs for SC lies between 450–352. So any thing above 350 will get you a medical college.

Even there are people whom i personally know who have got admission with below 350 marks in the past few years. If your state has got a lot cutoff this year then things can be achieved.  So rest assured n pray to God. Good luck. God bless.

Vishal, it's hard to get any government or private medical college even if you belong to SC category.. But don't feel dejected.. you can work hard this year again, keep all the ncert concepts at your fingertips, study hard with great determination and I am sure you will surely succeed in neet 2020 with flying colors.. Good luck..
