Hey,

It is no where mentioned that the fees for OBC category students are lower than the fees of general category student in private colleges of Maharashtra. Though you will get advantage in terms of lower cut off with the help of your category but fees in private colleges are same for everyone. There might be a possibility that one or two college provide some sort of scholarship to category student but generally the fees is just the same for everyone.

Bellow is a link stating the list of colleges of Maharashtra with their fee structure,

Hope that helps.

Thank you.
