How to learn junior high school mathematics well
1, improve classroom learning efficiency: Just do these three basic things well in class, that is, prepare well before class, follow the teacher's ideas closely in class, review in time after class, and absorb and digest knowledge in time is the king.

2, improve the efficiency of homework: when writing homework, you should finish it independently, and then compare the answers after writing. If the topic is written wrong, it means that you haven't mastered a certain knowledge point, so you should relearn everything you have mastered, so that you can make progress. And don't be distracted by other things when doing your homework.

3. Improve the calculation ability: Every math problem can only be solved by calculation. Sometimes, even if the idea is correct, but the calculation is wrong, you may get the wrong answer. So it's best to calculate by hand, not by heart, and check it again after finishing a question.
