Three points, the first point is the most basic concept and formula. This is the foundation of the problem, and your score is the most important. Concepts and formulas focus on understanding, not memory. As for how to understand, I'll teach you a way. Concepts and formulas in textbooks are usually followed by examples. Taking this example to understand concepts and formulas is vivid and easy to remember. The second point is to do more questions and brush more. It is best to brush one module at a time, and don't brush it indiscriminately. Because one module is brushed after another, you can use the formula more skillfully. Third, we should be good at summing up. Don't ask a question. Summarize those who can't make mistakes. In fact, summary is a deeper application of formulas and concepts. There will be changes in concepts and formulas and mixed tests in the test questions. If you can sum it up, I feel that you have made a qualitative leap. Fourth, review what you have learned from time to time. If you do the above three points, in fact, this is to spend the least time and get the most points, because a semester is still relatively long, and by the time of the final exam or even the college entrance examination, you have forgotten or are not skilled.

Finally, once again, concepts and formulas and the examples behind them are the most important, they are the foundation.
