Hello Jayyanth

No you should not mention your caste as OBC NCL if you don't have that caste certificate and you belong to general category.

You must enter your caste as GENERAL . If you don't do that your application form may be rejected.

OBC stands for other Backward class and NCL stands for non creamy layer that means the category in which patents income is less than 4 lakh per year. Also presenting caste certificate is mandatory,  without caste certificate no candidate will bd considered as obc ncl.

Candidates belonging to this category should meet the necessary eligibility criteria and certain documents for getting the benefits of reservations of seats.
