Hello,

Yes you are eligible for NEET 2021 examination. If you take admission last year in BDS don't worry you can give NEET again and qualified it. If you are getting MBBS this year you can admission it. But you have to submit some amount money for leaving BDS college because for your reason one BDS seat is blocked. After giving leaving money you can get admission any MBBS college. NEET 2021 application form is not release till now but it will release soon.
