Tell your instructor immediately, and just contact the Academic Affairs Office to inform you of the situation. Generally, tuition fees have two chances to be removed from the bank card. If you miss it twice, the computer of the academic affairs office should also be able to operate in the background. Just solve it as soon as possible, otherwise it will delay the course selection, so don't worry too much.

No problem. It is recommended to contact the counselor or class teacher first. You can also go to the academic affairs office and ask the teachers there where you can pay the tuition. They will tell you that if your tuition is not deducted, the bank will inform the school first, and the school will inform you to pay it in such and such a place. Generally speaking, the tuition fee for this semester should be handed in and registered successfully before your final exam, otherwise you are not qualified to take the final exam. There won't be any problems, don't worry.
