Don't brush the questions blindly. According to the way I used to learn mathematics, I must preview myself, and I must grasp several points in the preview. 1 I know what I know. I don't know. It's blurred after reading it. Listen carefully in class. And mathematical thinking is very important. If you have this idea, it is easy for you to learn. So I personally think it's useless to brush the problem, as long as you know how to solve it. That depends on thinking. Some math problems are solved. Look at the positive solution. If the positive solution is not good, it is a negative solution. Moreover, mathematics is more lively, so we must learn to turn. The turning point depends on whether you can find the turning point.

Active people think better than inactive people.

I hope it helps you.
