Thanks for the question  

The previous year's cutoff for SC category in haryana in state quota was around 424. 

So, there are negligible chances for you to get an admission in government colleges.

You should try for private medical colleges. 

Teerthanker Mahaveer University is one option which is good. 

All the best 

Hello,
Based upon your score in NEET 2018, and the previous year cutoff, chances are less for admission to Government Medical Colleges under All India Quota and state quota. You may have chances in Private Colleges at state level quota. Use NEET College Predictor to Check Your MBBS/BDS Chances in Deemed Universities & State Quota seat Based on Your NEET AIR
