No you are not eligible.

To be eligible if you are in caste like st/sc/obc/vj/nt then you need atleast 80/200.

For open you need 100 /200 just to be eligible.

Eligibility doesn't not guarantee a seat.

It is eligibility only for counselling rounds and preference filling forms..

Best of luck .

Yes you have a chance of getting BDS.You might get a government if not that then surely a privaep dental college you can get
