Hey Vardhan, EWS is newly introduced category so nothing can be said about it. The cutoffs would depend on the the difficulty level of the exam, number of students who have applied for JOSAA counseling, number of students who have opted for EWS category this time etc. So it is uncertain. You can check here for previous year's trends and cutoffs collegewise:- http://engineering.careers360.com/articles/jee-main-cutoff . Hope it helps!! Good luck!
