Hi , you haven't mentioned your category and assuming you belong to the state of your query so as per last year under 85% state quota minimum marks to secure a seat in government college from general category was 502 marks in government medical college,nalgonda ,426  from sc in government medical college suryapet,453 from ST in  government medical college suryapet and nalgonda  and 442  from obc in government medical college nalgonda

So as per last year data you have fair chances of getting a seat irrespective of your category.

Remember cutoff varies every year depending on number of students appearing in exam, difficulty level of exam, students scoring more than you and your category.
