Based on your score, there are good number of chances, that you might be able to get a self financed government Quota seat in any private dental college.

Hello aspirant,

With 286 marks, it is very difficult for you to get BDS seat even in private colleges.

As the cutoff under all categories in 2018 is nowhere closer to your score in All India Quota as well as state quota of Andhra Pradesh. 

For detailed information of cutoffs of previous year, you can refer to -
