hi,

I think you have graduated on bachelor of  dental surgery, see the eligibility criteria for mba in nit rourkela is candidates must have studies B. Tech. or B.E. or B. Arch. (with mathematics as one of the subjects in Class XII), or four year degree programme leading to B. Sc. Engineering (with Mathematics as one of the subjects in the UG programme), or four year degree programme leading to Bachelor of Science degree (with Mathematics as one of the subjects in the UG programme), or Master of Science ( with Mathematics as one of the subjects in the UG programme), or Master of Arts in Economics (with Mathematics as one of the subjects in the UG Programme) with aggregate of 65% or a CPI of 6.5 on a scale of 10 from any AICTE recognised institute. since you are from health science discipline and not having mathematics as a subject in graduation level makes you not eligible for the course. also admission is based on CAT score followed by GD and PI rounds.
