In fact, math is quite simple. Generally speaking, as long as students are not particularly poor and can do basic problems in class, they will always be careless. But the main scores in the math exam are not in these aspects. I think this is also the reason why many people hate math! Although I don't know whether your A and B volumes are the same as those of our school, I know that the questions in A volume are generally basic, while those in B volume are relatively difficult.

If you want to do a good job, you have to lay a good foundation now. A volume of more than 90 is nothing. Since the points are deducted, it shows that you still lack proficiency in basic topics. You can usually find some topics to do. I've been surfing the Internet recently, and I often look for some questions from the senior high school entrance examination a few years ago. I have done a lot, and it is still very effective. It is useless to learn math well by attending classes, and the accumulation of extracurricular problems is the most important. Before every mid-term and final exam, I will find some final questions, some of which I can't do, but I will understand my thinking after reading the analysis.

Doing problems is a method, but it also requires flexibility of thinking. If we always follow a routine to solve problems, I think it is hopeless to make mathematics top-notch. Flexible thinking is based on doing more questions.

This is what I summed up from primary school to grade three. I hope it helps you. In addition, I hope we can all get good grades in next year's senior high school entrance examination.
