The examination method of junior high school mathematics is basically what to learn and what to test. There are many obvious differences in high school math exams. Let's use a metaphor to illustrate it. For example, to learn carpentry, you must first learn to use various tools. How to take the exam? One way to test is to check the use level of your various tools in turn. If you can reach a certain level, you will learn the carpenter's craft well. This is the examination method of junior high school mathematics. Now another test method is put forward: provide you with suitable materials and spare parts and make a bench. It's up to you to find a way to solve the problem and realize your ideas. If you install four legs in turn on the table and then want to install four horizontal wings, it will be very difficult. Maybe your idea will never come true. This is the test method of high school mathematics. It tests students' ability to solve problems. More than half of the exam questions are unfamiliar topics, and candidates can't solve them by imitation. The hardest thing for students is that they have no ideas. Unable to analyze the question structure of the question to be answered. The original structure of the wooden stool is to cut four holes in the stool surface, then connect the four legs with horizontal wings and cover the stool surface. Some students have to chisel away the extra part of a square wood to form a perfect bench, which is time-consuming and laborious, and will make mistakes constantly in implementation. Students feel that they have learned all the methods, but they can't tell when to use which one. It seems that this really constitutes the main difference between junior high school and senior high school math exams. For example, the teacher keeps explaining riddles and analyzing their structure, characteristics, ideas and guessing methods. As a student, you have memorized all this, and it's still useless during the exam. You must have guessed a new riddle in the exam. It's about your abilities.
