I only got 20 points. Total score 150! They are all classmates in the same class. Good math scores are 145. It is not difficult for the teacher to talk about the examination paper of Zunyi city entrance examination. Your math foundation is too poor, so you should start with the foundation, pay attention to learning methods, strengthen the study of basic knowledge in junior high school, and abandon difficult problems, partial topics and strange questions.

Usually, we should understand the "why" when listening to lectures and doing problems.

Pay special attention to practice more: use your head and do it.
