Dear Applicant,

The last date to make any changes in the form was 28th March 2019. Now you will not be able to change your category and your application will go on board as it is. There won't be any significant change in the marks though for UR and EWS category, but, yes there will be a certain advantage to EWS students. Proceed for counselling now and see which seat you'll get.

All the best.
