Hello,

Hope you are doing well.

Normally as far as I am concerned if you belong from sc category then you should have to score 35 to 40 percent score of the total marks to have your seats in IIT. But dont think or resist yourself to this percentage as if you score more marks then your percentage or probability for getting seats in top and old colleges of iit will be increased. Meanwhile more marks means grabing your seats and your favourite branches within the comfortable zone. If you able to do this then you can easily get your seats in top most IIT like IIT bombay.

Further if you want to predict your college then you may use this college predictor tool as per your percentile in jee :-
