Hello, I'm glad to help you solve the problem. I have met them before. The following is my personal opinion. I hope I can help you. Please forgive me if there is any mistake! . Of course it doesn't make sense, but if you don't pay it, you can't pass it.

This fee is usually paid to your thesis supervisor. After you sort out the paper yourself, the tutor only needs to be responsible for the simple revision. This is a form. No matter how good the paper you organize yourself is, your paper will not pass without a tutor. Thank you very much for your patience. Please adopt it if it helps. Wish you a happy life! thank you
