Sagar;

With 300 marks , you are never safe for getting a govt seat in any medical colleges. For a general category student it lies around 550. Even for SC and ST category students; they have to score a minimum of 350+ to get a govt MBBS seat.

But with 300 marks you can easily study in private medical colleges with donation seats. Private colleges have such arrangements but no govt colleges are allowed for such policies.

Hope this helps and all the best!
