Hello Alviya,

As per the notification released by the NTA regarding economical weaker section quota (EWS)  only general candidate(whose family income below 8 lpa) are able to get benefits during the seat allocation by Jossa counseling. This means that students belonging to the EWS category will have 10% of the total seats alloted to general category students reserved for them. They will benefit as they will be able to compete for both the general category seats as well as the EWS category seats where the competition will be less.

Now, as per your question, sorry to say but since you have changed the category during the correction window, you won't be able to change the category as no editing is possible after the correction window and will be treated as EWS category candidate.
