Hi,

Admission to medical colleges also depends on Caste Category, State Quota, etc.

If you hold any caste reservation certificate, then with 500 marks, you have a great chance of getting a seat there.

With UR categeory, you may or may not get a seat there as cutoffs vary each year but 500 is a good score and you should definitely apply for it.

With 500 marks, you might be able to get admission to many other government colleges too. 

Check cutoffs at the given link to get a better idea->https://medicine.careers360.com/articles/neet-cut-off-for-government-colleges
