1. Find out the problem: First, you need to find out why you don't understand. Is it because the basic knowledge is not solid, or because the concept is not clear? Or is it because the learning method is incorrect? Finding out the problem is the first step to solve it.
2. Basic review: If you find that the basic knowledge is not solid, you need to take time to review. You can consolidate basic knowledge by doing exercises, reading textbooks or attending cram schools.
3. Ask for help: If you are in trouble, don't be afraid to ask for help. You can ask the teacher for advice or discuss with your classmates. Sometimes, other people's ideas and methods can help you understand the problem better.
4. Do more exercises: Mathematics is a subject that needs a lot of practice. By doing problems, you can better master concepts and methods and improve your problem-solving ability.
5. Make a study plan: Make a reasonable study plan and stick to it. Arrange a certain time to study math every day and review exercises as planned.
6. Adjust your learning method: If you find that your current learning method is not suitable for you, you can try to adjust it. For example, you can try to learn by watching video tutorials, taking online courses or using learning software.
