Dear student,

The general ews category was first introduced in 2019. So ews certificate for 2018 is completely useless and it doesn't make any sense.

So, you can produce 2019 ews certificate for the session 2019 - 2020 in csir and they will surely consider the 2019 ews certificate of yours.

Because for any session you have to present the category certificate of the first position year. Means if you are a 2019-20 session student, then you have to produce 2019 certificate. And suppose if you were 2018-2019 session candidate, then you have to produce 2018 certificate.

So, CSIR will consider of ews certificate of 2019.
