Hi aspirant,

It is not compulsory to attach the EWS certificate with the application form for the college you are applying into. Actually EWS certificate provides certain benefits to the people falling in this category and those who are eligible to avail the benefits of the same are required to attach the certificate as proof. Now in case you do not belong to this category or do not have this certificate, you can opt not to upload this certificate. Also not every institution of examination have reservation for EWS category.

Hope it helps!
