Remember, if you want to be a master, you should take notes on the wrong questions. What you did wrong is that others can't copy it and there is no information to provide, because your wrong question represents the defect that you need to supplement and understand.

You can use Wang Houxiong in science (I don't know if it suits you, but the overall topic is very good)

According to the survey, please don't cheat on the teacher unless your grades can pass the exam. The teacher is actually a good material. It's no pity that he told you such good material.

In addition, I don't want to follow the teacher like you (I am a master of science, and my math score can surpass the teacher), but I find that I can't. The teacher has some things that are not in the reference book, such as some problem-solving methods.

In addition, you can do some big problems or buy five years of real problem training.
