It doesn't matter that junior high school students have poor math foundation and senior high school students don't know anything. As long as you work harder than others, there will be no problem; The key is whether you have perseverance and want to learn. There are not many things about mathematics in junior high school, but in senior high school, teachers will talk a lot about knowledge in one class. This knowledge point has not been digested and understood, and the next knowledge point will pop up again, so day after day, more and more people will not understand it.

Suggestion: 1, put your mind right and recognize yourself (it has been achieved so far, very good). 2. Set goals and make up your mind (set short-term goals for yourself (next exam) and long-term goals (ideal university), arrange your daily schedule reasonably and make full use of every day. The key is to have enough perseverance and persistence, not to fish for three days and dry the net for two days. 3. Prepare a notebook for class every day, make notes to check for leaks, mark the blind spots involved in class in time, and take time to supplement after class (such as parallel line theorem, congruence, similarity and other knowledge points); In addition, you should prepare a wrong question book, collect the questions you think it is necessary to remember, and take them out for review before the exam. Of course, you have to make up the mathematical theory foundation of junior high school, because it is the foundation of this tall building in senior high school. If the foundation is unstable, it will easily collapse. 5. The mountain of mathematics is not terrible. The terrible thing is that you don't have the courage to face it. Everyone is the same. You have to think about what you want before you can work hard for it, for yourself, for your family and for the future. Come on, kid! ! ! Limited ability, hope to help you, welcome long-term communication (one month later, six months later, one year later, three years later. . . I'm still here)!
