hi,

as for gate 2021 official brochure, OBC-NCL and EWS candidates are NOT required to submit / upload any category certificate while filling the online application form. however during the time of admission or psus interview you have to show the updated certificate. however due to covid 19 pandemic the

up dation process has slowed down for different certificate related issues. so I guess it would not be an issue and your candidature would remain as qualified.
