Dear student,

For the scholarship you have to fill the online form and give details about you category, domicile and income there and you have to submit the two set of documents mentioned below:

And these documents are verified by the college first and then they forward it to the scholarship giving authority, so if you do not submit the category certificate in the college and you claim to belong to be an OBC candidate in scholarship form that might cause an issue, but if you genuinely are a OBC candidate an application to the college authority can solve your problem.

The exact details about it, can only be given by the college authority so I suggest you contact them or visit them during college hours and ask you query.
