Hello , 

As your query is you have scored 450 marks in in the Neet exam and you are an OBC candidate well what college you can obtain is all depended on the Neet counselling process therefore you need to wait for that and there is no such particular college where there is low fee for medical all you need to do is to apply for the counselling process since you are an OBC candidate therefore definitely there will be a help in the fee for you but at first you need to find the college therefore involved in the counselling process of Neet.

if you need any other detail you can let me know in the comments section below we will definitely help you with that. 

I hope your query is solved.

Thank you.

Hello Navya, all colleges taking in admission through NEET counselling for medical follows a common fee pattern.
However you can get subsidies, and fee refund through your OBC category and also if you belong to lower economic sections. there are ample welfare schemes by the tamil nadu govt too. check out this link: http://www.tn.gov.in/scheme/department_wise/28
