Hi there,

Sorry to say but you can not use EWS certificate as your caste certificate because there is a huge difference in both the certificates. You can not even submit your ews certificate when you were asked to submit caste certificate.

Failing of sitting any particular document will result in your cancelation of application. See, the document verification is super important in any field. If you fail to submit the original document or the actual document then definitely nothing would be done to protect your application for cancelation.

So fill your documents will proper serial number and with accuracy.

I hope this information helps you.

Revert in case of any query.  Thank you!
