Dear Sharda, in 2018 under State Quota a score between 402 to 520 secured a BDS seat in Government Dental College under OBC Category. That was 2018 data. With 391 marks it is difficult because this year the cut offs have gone way higher and Cabdidates at 520 also are unable to get MBBS seats. Which means they try for BDS seats thereby increasing the BDS cut offs and decreasing your chances.
