1. Listening carefully in class is a necessary requirement at any learning stage. Learn from the teacher, because the university teacher talks over and over again, and there is no time and opportunity to sharpen his knowledge.

2. take notes! Be sure to take notes! In particular, the knowledge points that have been talked about once in professional courses can't be remembered, and if you don't take notes, you can only be numb at the end of the period. The notes should be divided into lines, and the key points should be marked with eye-catching colors. Especially the example of remembering many high numbers. The picture below is my high number notes.

3. Spend more time in the library and study room. Don't do nothing when there is no class or homework, but preview and review spontaneously. Otherwise, I will be very busy during the final exam week. Review frequently, and check for missing parts. Read more information. Be more independent and abandon the inertia of being driven away by the teacher. No one cares what you study in college, you can only rely on yourself.
