When did you graduate? You can refer to my own. I went to college in 2007, and the student loan in 2008 and 2009, that is, 10 was repaid in June when I graduated. I was not interested at the time. If I pay it back after this time, I will need interest, so I should save some money when I practice. After the internship, it should be almost possible to return them.
Generally speaking, you still need interest. Ask when you borrow money. Policies may be different from year to year.
