Therefore, I suggest that class notes can be put aside first, not recorded, or a small number of topics recorded. Understanding is the key. Our teacher said that learning does not depend on money and time. Some students, if they buy beautiful notebooks and move knowledge points from one book to another, still can't, or have been learning, but they can't. But take the teacher's notes, and remember everything. Therefore, I suggest that you listen first in class, count as much as you listen, and then borrow your classmates' notes after you come down (there are always classmates who make neat notes in each class but don't attend classes). If you don't understand, you must find teachers and classmates to understand those things. Don't buy reference books or workbooks without understanding (wasting time, giving up the basics), just look at the topics mentioned by the teacher and the topics in the textbook.
In addition, if you don't understand, don't keep pestering here, just assume that you understand, keep talking with the teacher and ask again after class. This can't be written down. Remember, don't let notes become a form.
When you learn your grades well, you won't learn less and remember less in class, so it will be easier. I don't remember what you will do. I don't remember what's in the book. The key is to know.
