Hello Divya,

You need to tell us your All India Rank to know if you can get a seat through All India Quota or not as seats are allotted according to your All India Rank. 

If you have scored more than 550 marks then you have decent chances for admission to Government Medical Colleges under All India Quota and state quota.

You can go through the previous years cut off of various government colleges to get some idea using the link - https://medicine.careers360.com/articles/neet-cut-off

You can also use NEET College Predictor to Check Your MBBS/BDS Chances in All India Quota, Deemed Universities & State Quota seat Based on Your NEET AIR.
