Dear aspirant hope you are doing well..

Fees for in each category is for different in each college. It  means fee for unreserved, obc, st and sc are fixed in each college. It obviously that fee structure of obc category candidate is lower than unreserved, similarly fee structure of sc category candidate is lower than obc and fee structure of st category candidate is lower than sc category candidate. Fee structure have different slab for different category. It aslo give reservation in terms of seat..
