hey!

EWS (economically weaker section) category is a subcategory of General category, generally, it is referred as GEN-EWS means general EWS category. And you do not fall under OBC/SC or ST category.

So, when you fill the form, it shows OC (other category) which is an alternative (only in forms) for genral category or Unreserved (UR). Don't worry, you still will be considered EWS category candidate if you have EWS certificate.

Hope I answered your query.

Thankyou
