In addition, if there is a library next to your school, especially the university library, students can borrow library cards and books for self-study.
Personally, I think Cheng's General Physics (the fifth edition will do, divided into three volumes) is good. You can buy it on Dangdang, or you can buy a matching counseling book.
Let's start with general physics.
Personally, when studying physics, it is best to refer to different textbooks, such as optics. At that time, I referred to three or four books. Some are popular and easy to understand, and some have more contents, which complement each other. It's good.
In addition, regarding mathematics, we should learn advanced mathematics well. Wen Li, I think Wu's advanced mathematics is ok and suitable for self-study. It's best to buy reference books and the like when studying by yourself, such as "A Guide to Advanced Mathematics Self-study", and search in Dangdang or Xinhua Bookstore.
Besides, books are generally only suitable for you. You'd better go to Xinhua Bookstore, where books are generally complete, including physics, advanced mathematics textbooks and so on. See for yourself and choose what you can understand.
