Hello Buddy! Hope you're doing good.

As your OBC-NCL certificate is of this year but according to the guidelines the category certificate shouldn't have to exceed 1 APRIL, 2021. So your category certificate will not be valid in JOSSA counselling. So kindly update your category certificate, you have certain time for this otherwise you will be treated as a general candidate in the JOSAA Counselling. Hope this will help you.

ALL THE BEST! WORK HARD !!
