First of all, you should be interested, second, you should be determined, and third, you should be patient. Finally, study hard. Starting from the basics-familiar with skills-application. I must have practiced it countless times. Ask the teacher for specific study. If you want to learn well, you must find a suitable learning method, understand the characteristics of the subject, recite formulas, think more, dig more and do more problems. There is no shortcut to learning, only practice, practice and practice again.
Do a good job in four rounds of study:
1. Review the basic knowledge comprehensively (see the textbook).
2. Analyze the existing problems in detail, and do a good job of leak detection.
3. Review section by section. To achieve similarities and differences, differences and similarities.
4. Special review. Cultivate comprehensive ability and expand their application ability.
Wish you success!
