Before anything could be said about what colleges you can get on the basis of your score in NEET, you should know that it would be too early to predict anything. The cut off trends tend to change every year and same can be expected for this year as well. However, for your given score, you have a  chance to get into a good college due your category. If you want a decent level college you should have achieved a score of 500+ as UR candidate. But you can try the college predictor for further information about colleges:
