Hey,

You wil have to provide your EWS certificate at the time of registering for the entrance exam. So definitely you will be needing the certificate. But as far as the next year is concerned you will have to apply for your EWS certificate again as that would be expired till you take admission in the college.

They will inform you in advance about that and will even give you some time to get your certificate reissued. So don't worry about that.

Hope that helps.

Thank you.
