Hi Aspirant,

Hope you are doing great as per the question asked by you, as you can certainly fill the N.I.M.C.E.T form with old O.B.C certificate as in further process of counselling or admissions the forms are reopened at that time you can certainly upload the new O.B.C certificate.O.B.C certificate need to be updated after 1 april 2022 so you are advised to get it updated by visiting it to the nearest tehsil or S.D.M office. Validity of any category certificate is till 1 april after it you need to renew it.

Hope you found this answer useful. Stay motivated stay positive.

All the best!
