Did you mean SEBC? If that is so, SEBC is not a National level Category. It is not in use in all the States but NEET application on the other hand is released across India in the same manner. And so if you belong to SEBC and your community is listed in the Central OBC list, then you should be selecting OBC as your Category. But if the Community you belong to is not listed in the Central OBC list, the you should select your Category as Open Category. But while registering for State Counselling, you can select SEBC as your Category and avail its benefits.
