I come from Wuhan. If I repay, there are two ways: prepayment and normal repayment. If you choose to prepay, you need to write an application for prepayment, which is very simple. Then you need to log in to the student source aid system and enter your loan page. There is a column for applying for prepayment. You click in and select your loan contract number in the contract selection column, and it will automatically generate other information. You just need to check it last, and then click OK. (If you pay off all at once, you may need to fill in the loan quantity in turn. In addition, the prepayment is1-10 on10 every year, and the prepayment application also needs to be submitted during this period. In other words, if you plan to repay the loan in August, you must apply on August 1- 10, and put the money into Alipay before August 10. The minimum repayment amount is 6000, or 12000 or 18000. In short, it is how much. In addition, the interest will be calculated from September 1 day of the graduation year, and no interest will be paid before that.
Alipay's account number, this should be marked on the contract when borrowing money, (it's really not good, you can ask the local capital center)
Finally, the issue of interest, you can directly enter your loan system, which has the principal repayment query and interest explanation. Very detailed, including the amount of your normal repayment. I suggest you take a closer look.
That's all I know.
