Secondly, you can't think that if you understand in class, you will do it; It was the same at first, but later it was a mess. You should constantly revisit this problem, understand how it is solved, and think about the origin of each step. The problems in high school are constantly changing, but the thinking will basically remain unchanged. You should master this idea and be able to react when you do the problem.
As for homework, I don't know if your teacher left you the answer to your homework. If so, that's best. If not, then prepare a learning APP and check the answer at any time. Of course, the answer should be checked after you finish the question, but if you think about a question for more than five to fifteen minutes (the maximum time limit), then you should check the answer, and you should try to solve it yourself while relying on the tips given by the answer. Never copy! Read it after you finish it.
Finally, prepare a wrong book, copy down the wrong questions, and then save an answer that you can understand. You can try to write it yourself in your review or leisure time to see if it is correct. If you are wrong, ask your classmates or teachers for help, then mark a symbol before or after this topic, mark it wrong once, and see if you can write it in the final exam. You can also mark the wrong questions you have mastered and have a rough look at them when reviewing in the future.
Also, pay attention to the allocation of time. The college entrance examination can take more than just math.
Always do the questions! Always do the questions! Always do the questions! Say the important things three times
I hope my answer is helpful to you. I wish you progress in your study. Come on!
