Yes, the improvement of math scores is inseparable from the necessary brushing. First of all, you need to think more and use all the methods you can think of. If you really can't figure it out, let's see how the answer is solved. If you don't understand, you can ask the teacher, ask your classmates and, of course, ask your friends to summarize the method (or summarize it with other similar topics). If it really doesn't work, give up this question, because after all, you are incapable.

If it is done, but it is difficult, I suggest you see how the answer is solved, whether it provides different ideas or solutions, sum up and expand your ideas.

If you are free, you can prepare a notebook, extract all the good questions and wrong questions, and review them later to see if you can do it again.

However, if the title of your book is better and you take it as seriously as I do, I think you will make progress. Come on! If your foundation is weak, I suggest you don't do difficult problems and digress, because this will only get twice the result with half the effort. )
