Hi 

As per your query I would like to tell you that last year least marks to score a seat in Madras medical college and kiplauk medical college was 457 and 393 marks respectively from your category under state quota. This year's cutoff has not be provided officially yet. So as per that you need to score marks around these . Talking of which remember that cutoff varies every year depending on number of students appearing in exam, difficulty level of exam, students scoring more than you and your category.

Hope this helps
