This is an unpopular but surprisingly effective way to improve math scores. The solution is that if you can't work out a problem you can't understand, you can recite it without taking the time to understand it, but don't recite everything. You should recite moderately difficult questions. You don't usually need it in the future if it's difficult. Do it yourself if it's simple. After doing this for a period of time, you will find that you have saved a lot of time, and you will also "set answers" to questions that you can't answer.

2. Review after class

One thing that high school mathematics must pay attention to is timeliness, and it must be reviewed in time after class. The reason for this is that if you read it every few days, you will find that you have almost forgotten your knowledge. Reviewing at this time will not yield much, which is equivalent to relearning. Therefore, the idiom "strike while the iron is hot" is also applicable to high school mathematics learning. Secondly, the knowledge we review is not once and for all. It is best to summarize it every week and every month. This will help to form our knowledge network and make it easier to remember.
