Well, if you go to the textbook teacher, he will naturally register and tell you which ones are in your class. You just need to take the list and lead the students to recite it. Our school has a course selection system, which includes whether to order textbooks or not, and according to that, the total number is calculated, that is, how many books have been collected in a class, such as a college in Grade 08. Generally, the book fees of universities will be paid at the beginning of the semester, and it is definitely impossible to pay directly to the textbook teacher. If it is corrupt, it will be directly handed over to the financial department for unified collection, and they will issue a receipt, which is proof. You may be asked to show these certificates when you graduate, if not. Might make up the money. In short, listen to the teacher.
