I am finding it difficult to choose between BDS through COMEDK and BSc.Please suggest me what to choose as my career.

I have always been interested in MBBS, but this year due to stiff competition in COMEDK inspite of having a score of 125, my rank is 7422. So for such a rank I am only eligible for BDS, about which I know only a little. Please advise me which one to opt- BSc or BDS.{I am also interested in BSc}
