Hi dear,

Your fee structure will change after 1st semester. In your 1st semester you have to pay around 86k as your college fee and around 31k as your hostel and mess fee. after 1st semester you have to not pay one time fee and other fee so it will decrease after 1st semester. If you have income under 1 lacs then you will get 100 percent tuition fee waiver I.e. 62500 or if your income is between 1 lac to 5 lacs then you have to pay 1/3 of tuition fee. You can also check fee structure here
