First: First of all, you are sleepy in math, but it is cruel to study hard! I remember that at first my deskmate and I supervised each other. At first, when they were not in class, they abused each other and pinched each other. In the first week, my arms and I were basically bruised. The second week was short, so we got rid of many bad habits!

Second: take notes: this is very important, ok.

It is true that it is better to take a rotten pen than to remember, because when taking notes, we will wish the newcomers to take notes. There may be some interference at first, but the back will be fine.

Third: embrace boredom: learning is boring, so you should deepen it. When you are studying and nothing else can interfere with you, you are not good at any subject.

I remember when I was really a sophomore. At that time, I gave up mathematics and felt that I couldn't learn it. Fortunately, I met a good teacher whose strict requirements made me get good grades in high school mathematics. In fact, no matter when, it is never too late to study.
