Hello, 

It's not easy to predict other expenditures other than Tution fees but I am providing the below given link to help you :

Hostel fee is around 75000 per year, while around 1 lakh is the total caution fee deposited in the college. There are also some kind of hostel caution money, admission fee, etc.

Good luck!!!
