Hi, 

Well even in bds course the competition is high and the cut offs aren't dt low as compared to that of mbbs.

So you need to have a score of above 510-520 as a safe score.

With ur marks getting govt bds seat is lil difficult. But you can apply for deemed/private colleges. You can have a fair chance there.

But dres also d fact that nothing can be said with certainity since the trends and cutoffs vary every year. 

All the best.
