Respected sir/mam
I am studying bpt at sikkim manipal institute of medical sciences, 2015 batch, yet i am still studying in 2nd year. I haven't attended classes since 1 year and i have paid my fees till 3rd year and now i wish to withdraw from the course, i was said to pay 50% of tuition fees of final year. What is the actual policy of withdrawing? Do i have to pay?
