Speculation is definitely not the solution to the problem.
When taking the exam, we mainly focus on the previous choices and fill in the blanks, because it is generally not difficult, but we must also choose two wrong ones and fill in the blanks with one wrong one. You must spend more time here than others, but in the meantime, you should grasp your own mentality. You can't worry about what others are doing, and then ignore the front and do things you are not sure about.
As for the big questions behind, especially the first two questions, we must win. Generally, the first two questions are nothing more than trigonometric function and probability, and almost everyone can get the trigonometric function. As for probability, it's actually very easy, but it may be a bit novel at first. Many people don't care. As a result, this subtitle is unskilled or indirect. If you don't master it well, it is strongly recommended to read the textbook in the last few days. Just take a good look at the problems in reading.
In this way, you can take one hundred if you are good. If there are some mistakes in the middle, it is not difficult to pass. Of course, it's up to you.
I wish you success in the exam.
