hi,

see the cutoff score varies year to year and depends on certain facts like number of participants, questions difficulty level, seat matrix, state wise students performance since 85% seats in every government institute is reserve for domicile candidates. now see if you have applied from ews category you would allot seat as per ews cutoff. however it is quite difficult to predict the cutoff since exam has not taken place and it also depends on questions difficulty level.

so try to score as high as possible.

There is no free seat concept. We have Government Medical Colleges, Private Medical Colleges and Deemed/Central Universities. And again in Private Medical Colleges, there is Government Quota. The lowest fee structure is in Government Medical Colleges. Now you haven't mentioned your State. This is important because cut offs also depend on the State you hold the domicile of. But in general, 400 might be tad less for a seat in a Government College. If you belong to EWS Category, you need to score atleast 475-500 again, depending on the State you belong to.
