The thinking is not clear! Doing problems is often complicated by unclear thinking. When you see a problem, you will always think of many related problems, solutions, even what the teacher said when talking about the same type of problems, students' reactions and so on. You should study very well, and you have great potential. All you have to do upstairs is calm, don't panic, be confident and so on, which can't solve the problem fundamentally. All you have to do is clear your mind. If you feel more and more confused, then you need to make a summary. To sum up the general practice of each question type, you should generally ask the teacher what questions are in the exam, how to solve each question type or how to understand the words in the question (some questions always change a sentence into another way, then you should know what the original words are, in the words of my math teacher, "How to translate this sentence?" ) or what you think of when you see any conditions. After asking the teacher, you can find the questions you have done before and think with the general ideas told by the teacher (you don't have to find new questions to do, you don't have time to do them, you can find some small questions), so that you can get familiar with the new methods of doing them as soon as possible. That's all. I wish you good luck in the exam and get into an ideal high school.
