1. Learn to integrate concepts and formulas: don't just stick to the literal meaning of concepts, don't memorize them. Learn to dig the essence of formulas, just as you know the principle of a machine, so you will know how it works.

2. Start from the foundation: the foundation is like a tall building. Only when the foundation is stable can the floor be stable; Don't blindly follow everyone's footsteps and find your own rhythm. It is suggested to sort out the most basic knowledge points in the four-round review of mathematics in the senior high school entrance examination, and combine examples to seriously think and solve problems.

3. Summarize similar questions: learn to summarize questions, classify the questions you have done, know which questions can be solved, how to solve them, which results can be mastered, and which questions you can't do, and make good use of the wrong problem book.

Learning is a protracted war, and it needs constant persistence to see a qualitative leap.
