First of all, there is a problem with mentality, and it is impossible to learn badly.

If you want to learn well, you must first adjust your mentality. You can't say that you like this subject completely, at least you can't hate it. It's useless to learn it well.

After the mentality is adjusted, it depends on your own efforts.

Mathematics is a science, with a variety of questions, but no matter how the questions change, the test sites will not change. You can do a sea tactics when you have time, but you must understand it. If you can't do it, everything else can be ignored. You'd better find someone to help you correct it. Chinese and English are liberal arts. Be sure to remember what a word is "memorized", and it is best to write down what the teacher said, so that there will be materials to review in the future, and the topic will come alive. The most important thing is understanding and methods. It is useful to do more useful things, but it will not have good results in the short term.

There is also class, we must listen carefully, no matter what subjects, we must listen carefully and remember carefully. Ask if you don't understand. If it is not convenient to ask questions in class, be sure to ask after class. You must understand more than 95% of what the teacher said that day. Don't have "overnight meals", it will accumulate more and more things you don't understand, and you won't know anything during the exam.

In short, we must adjust our mentality.
