I think the effect varies from person to person. This set of teaching AIDS is suitable for horizontal homework, that is, for a certain type of questions. I suggest that you use this practice method for your weak or intensive problems (full marks), such as trigonometric problems, such as solid geometry, such as solving several problems, such as probability. I was aiming at understanding a few things. You can fill in the blanks with the answers and review them before you do it. Better explain the previous one. . . When you do a lot of questions on the same knowledge point at once, you will know what to take in the exam and you will have confidence. The key is to persist in and analyze the causes of mistakes.

Also, if you make a mountain out of a molehill, there are two situations:

A (you are a senior three), for me, I was holding a small notebook, and I copied some small questions randomly from it every day and recorded the page numbers. When I had some water lessons, I did it at the bottom. . . After all, such a big book is inconvenient, isn't it?

B (Senior Three) The key to a small problem is speed and accuracy. I suggest you buy several sets of papers (specially used to fill in the blanks above). If you do more, you will feel it. You should be good at classifying the questions you have done in your mind. Note that it must be limited. Fill in the blanks, generally limited to 40 minutes, if the degree is good, it will take about 25 minutes.
