Good luck.

Either you have no idea what a management education is. I hope you are aware what an IIM is, if not please do search it on google. IIM Kolkata, IIM Ahmedabad, IIM Bangalore, IIM Indore and IIM Kozhikode are top institutes in India.

No, the chances for the medical seat with 180 marks are extremely low but if you belong to any of the reserved categories` then, you may get admission in a private dental college.
