One: Listen carefully in class. My senior math teacher speaks very well. I will listen carefully to the explanations of knowledge points and the exercises in class, and take notes carefully. I think this is very important. Of course, if you miss the previous knowledge points, you can find online courses. After all, online courses are rich in resources, and most students will learn advanced mathematics, so online courses will be more abundant.

Two: consolidate in time after class. I wonder if you will leave your homework. When I was studying this course, I had online work, and I could always brush it before the deadline, but the topic was different every time, and this homework score was included in my usual grades as part of the total score. At that time, in order to get a higher score, I almost brushed all my homework to 100. If there is no homework, you can do a topic explained by the teacher in class, which is generally more important.

Three: review in time before the exam. Some students think that they usually study very well, for example, they are serious in class and homework, so they ignore review, but this is absolutely not desirable. Even if they study hard at ordinary times, it is very necessary to review before the exam. Because a college class is very long, at least 90 minutes, the content of a chapter can often be memorized in a short time, which is difficult for an ordinary person to remember for a long time, so it is very necessary to review before the exam.

Four: preview. I have never done this job, because I often forget it, and because I am lazy. But preview is definitely good for you. After previewing yourself, you can generally know what the content is, which makes it easier to understand and keep up with the teacher's rhythm in the process of speaking.

This is my suggestion. I have done one or two things, and the fourth point has only been tried several times, and I have never persisted. I hope my answer is helpful to you.
