Hey,

See, this year's cut off marks are higher than previous years. So a SC candidate would require a minimum of 470+ to get a government college . Your marks is really low compared to the cut offs of various government colleges. Still  you can wait for the results of third round counsellings. If luck favours you will make it up this year. Even if you don't get a seat, don't be disheartened, take an year off and prepare well for NEET 2020.

All the best
