Hello student, 

With a score of 300, it becomes difficult to secure a seat in the self financed medical colleges in Gujarat when comparing the results of previous years. Last year,  a  minimum score of 380 was required to secure a seat in Parul institute of medical sciences and research, Vadodara in OBC category under the state quota. But scores and ranks vary each year with difficulty level of the question paper and availability of seats. However you can predict the colleges which you are likely to get using the given link
