Hello Ankush Rana, you will not get any MBBS course in any government medical course with the score of 300 being a general candidate,but you can get private medical college but they will cost much in terms of fee for you.you might get dental with this score but if you state cutoff is too, for a general state like bihar and up you will not get Dental also.For getting MBBS seat in government medical college your score must be greater than atleast 500 depending upon your state like for Bihar around 570, Jharkhand 550 etc.
