The last question is often difficult, and there are usually three questions. Write only the first two small questions to ensure the score. When reading the questions, mark the conditions in the picture with a pencil. The first sub-question is relatively basic, just set it inside according to the formula. The second sub-topic is a little more difficult and may move. Draw it with a pencil, analyze its moving direction, and analyze its angle and geometric properties. The third question belongs to the type of excellent class, and there may be more difficult exercises or classified discussions. As long as you calm down and analyze slowly, it doesn't matter if the question is wrong. I was nervous, too. My teacher is very strict. If I make a mistake, I will be punished. You just need to make sure that all the choices are correct. That's what our teacher said. This is also based on my junior high school experience. For reference only!
