First of all, you need to know whether your school's failing grades will be reflected in the official transcripts (some schools will directly cover them without leaving a trace, some schools will mark them as ※, and some schools will not directly cover them), because basically all schools are required to hand in the transcripts of all the courses they have studied during the second interview, and if there are traces of failing, it will become a potential deduction for the second interview, so you should be prepared to explain it to the teacher during the interview (the teacher does not ask you, so you don't have to explain it specially).

Secondly, it has no effect on the initial test, but if you want to take the math test, you must pay more attention.
