Senior high school mathematics is much more difficult than junior high school mathematics, and senior high school mathematics is not directly deepened on the basis of junior high school mathematics, so we can't judge senior high school mathematics scores only by junior high school mathematics scores.

In fact, this situation is normal in the first two monthly exams of senior one in second-and third-tier cities. The main reasons are that learning is more difficult, subjects are increased, and learning methods are not in place.

There is a lot of knowledge in high school, so we must make it slowly and steadily, step by step, and don't default, because it is basically difficult for high school to make up casually like junior high school. It is suggested to adjust the learning methods. Every time you learn a knowledge point, you must master a knowledge point, analyze the explanation ideas of the textbook, and count the wrong questions, so that it will be easier to learn.
