Sir,if we filled ews category in jee mains form,but not able to get certificate,will we then come back under general category automatically?

Dear Sayisha, It is a new type of reservation that the Govt. has come up with⁩ . So putting this reservation into force will take time. But all you need for this EWS certificate is 3 documents: Date of birth, nativity certificate and income certificate. The Tehsildar will issue the certificate. This is the process. If you have the documents, though it will take time you will get it. Lets talk about the timeline here. The exam is in May, the counselling will start way after. And we are in March. So you have ample of time to get the certificate done. Inspite of all this, just to answer your question, you cannot change your Category again from EWS to General. But we would suggest you to select EWS and then work on getting the certificate done.
