Hello Aspirant,

See if you belongs to OBC- NCL category then you can take admission through either General category or under OBC reservation quota but if you will take admission under OBC reservation quota then you must have to produce the OBC-NCL certificate but if you take admission through General rank under General category then there is no need of any certificate.

Not only in NEET  but in other fields or exams it is  same process if you are showing your category as OBC then you must have valid certificate for it.

I hope this information helps you.

Good Luck!!
