Hi Jessica,

You have not mentioned your category so I am assuming it to be general.

For MBBS ,BAMS and BDS you need to score more than 450 to get into government college. For BAMS a score of more than 400 will get you in any semi government college and a score more than 350 will be required to get into any private college.

For BHMS you have to score more than 350.

Now coming to second part of your question. There are practically less chances for anyone to get into college with low fee structure with score around 300 because this kind of fee structure you can expect only in government colleges.
