I think the best reference book is "Five-year College Entrance Examination, Three-year Simulation", or 53 for short. We all use this book, and it is quite comprehensive, which is good for self-study, and it is published by Beijing Normal University Press, which is quite reassuring. Because of this book, my previous math scores have improved a lot.
Followed by "point push", I have been using it from junior high school to high school. After each chapter, there is a chapter test, and then there is a reflection on your own shortcomings, just like the wrong set of questions, which is very beneficial to self-study.
Also, the complete interpretation of the textbook is ok, and the explanation is complete, but the exercises are not very classic, and the exercises of "Hug and 53" are good, and the answers are very detailed.
You can go to the bookstore to look at these books and then decide whether to buy them. I hope it helps you ~
In addition, I suggest you buy some classic papers and do them one by one. You can revise your answers after you finish, which is especially helpful to improve your math scores. Especially when we review in senior three, almost every day except the teacher's homework, everyone is doing papers, which is very effective.
Finally, I would like to remind you that the wrong questions you have done are very important. You'd better have a set of wrong questions, especially in math class.
That's all, I hope I can really help you, come on ~
