Aryan, there is EWS reservation for admission to IIM Indore for its 5 year Integrated Management Course. If you look at its brochure in Page no# 4 at the link, file:///C:/Users/dell/Downloads/IPM-Domestic_Applicants.pdf (file:///C%3A/Users/dell/Downloads/IPM-Domestic_Applicants.pdf) , it says that the available reservations are NC-OBC,SC,ST and EWS. Now we are not aware of the reason why the certificate format has been taken off, but EWS reservations is available at IIM.
