There are 2 ways about it, Pratap. You belong to SEBC Category but you do not want to claim it for whatsoever reasons. Then you can select "General Category" as your category and let go off the reservation. In that way, you cannot be eligible for SEBC reservation but you can try to get a seat in General Category based on your NEET score and rank in the merit list. Now let's say you have selected SEBC as your reservation category, you have to submit your documents during document verification. Now if you decide that you do not want to use SEBC reservation and do not submit the documents, you will not be considered under General Category. Your admission will stand cancelled. You cannot change your Category at a later stage during the admission or counselling process. You have to select the Category that you want to and stick to it and produce relevant documents during document verification, counselling and admission.
