Hey Rimsha!

You may or may not have chances for government colleges as in your case , it all depends on your state.

In some states , the cutoffs for government colleges are 600+ while in some states , the cutoffs for government colleges can also be 450+. So you may have good chances in latter , but not in former. 

Well , your score is good , so hopefully you can have chances for government colleges under state quota . But it is not sure as it depends upon your state. So , please do mention the name of state in comments. 

Or ,
