Hello, Manu 

It would be difficult for me say that you will definitely get a government college because cut off is different every year depending on category home state etc 

However, 500+ is a score where you can get a government college and you are no way near that you will not get any government college 

Hope this helps you if you have any queries you can add in comment section

Thank you

J&k has article 370 according to which we our state has different cut off from other states
