Hello aspirant,

Hope you are doing well. EWS category is introduced very late this year only so everyone was confused and many got to know about it very late and if you have not registered as a ews candidate in JEE main and now you can register for it in JEE advanced as during the registration process you must change your category or at the time of correction period you must change your category by giving the required category certificate.

Hope this helps

If any queries feel free to ask

All the best!!

Regards
