It is very important to fill in the blanks, and nearly half of the scores must be taken seriously. Therefore, in order to overcome sloppy and unfamiliar questions, it is best to make a set of choices to fill in the blanks every day to keep the feel, and then answer the questions. The first 3.4 questions are basically common questions, and there is a unified solution to the solid geometry of probability trigonometric function. If these questions can be stabilized, basically a good result can be achieved. If you want to get into high school, you should focus on the last two big questions and try your best to do them, because these questions are often the place to distinguish ordinary candidates from excellent candidates, and it takes a lot of time. If you are a senior three, I suggest you give up other subjects and try to use them by hand.
