Coming to the fee structure.

Fee structure will depend upon the type of college and type of seat you get. If you get a govt. College than your fee will be in range of 50000-80000/a , if you get seat in private colleges that will further depend upon the college to college but range will be 6-10 lac/a. 

Good luck
