Hello Rachana,
I would like to tell you that  your score in NEET 2018 isn't that good, and based upon the previous year cutoff, chances are less for admission to Government Medical Colleges under All India Quota. You may have chances for admission to government colleges under state quota. Use NEET College Predictor to Check Your MBBS/BDS Chances in All India Quota, Deemed Universities & State Quota seat Based on Your NEET AIR
