Hello Meenakshi 

You haven't mentioned your category which really plays an important role to get college. Your score is decent but if you belong to general category then under AIQ you cannot get bds course in medical college as for that you should score minimum 500+ marks but if you belong to sc/st category you may get bds course under AIQ. 

Use Neet college predictor to know the colleges you can expect with your rank
