I am a liberal arts student, and my math foundation is very poor. Learning math makes me very tired. I want to ask if it is useful for you to make a corrected copy to improve your math scores. thank you Most methods are tried to know whether they are useful or not. The key is to have a good attitude.

Stick to what is really useful, and there is no need to follow others when it is useless.

What suits you is the best.

Go shopping under pressure, don't stick to one place.
