1. Foundation: First of all, we should practice the foundation. Qidong Middle School's exercise books and winning the championship lightly are very good. Neither of these questions is particularly difficult. The practice foundation is very useful and the answer is clearly explained. The light championship is divided into gold edition and silver edition. If the foundation is not solid, you can buy the gold edition, which has many explanations of this unit.
2. Difficult classics: This has been improved, and geometry is very important in future study. The following book is one that I value very much. It's a book of every grade. The questions in it are difficult, but they are all good questions, especially the geometry questions, which are really good. It is helpful to practice this with additional questions or questions during the exam. The answer is also very detailed, which is a very good book.
I usually buy these (you don't have to buy them all, just choose the ones you are interested in), and the most important thing is to attend classes. These are still auxiliary tools, and more practice is also very helpful ~
Anyway, I hope I can help you ~
