You will have two types of fee :tuition fee and college fee(but if you are far from college, then you have to pay for college bus also)

Tuition fee:you said you belong to SC.. So, your tuition fee is paid by government  for that you should apply (get that information from the college ), otherwise you have to pay again(so, kindly ask about the scholarship and submission dates, get in touch with them)...

College fee:this college fee should be paid compulsory by you... That depends on college to college.. This fee includes library, books for every semester etc..

Bonus :after completion of your firs training year you will get extra 5k/- from government...

I hope you got the answer! :-)
