Analysis:

(1) Take an active part in lectures/after-class tutoring, and the questions will be answered.
(2) Take the initiative to ask questions to the math teacher/tutor, so that they can feel your strong enthusiasm for learning and the determination of the prodigal son to return.
(3) Specify the topic, the topic of previous years, and practice it several times with gourd painting gourd ladle. Even if you don't know anything, practice a few times more, and maybe you can understand something.

PS:
The scum of the first test 40 and the make-up test 99 drifted by. Good luck.
