My personal opinion: If you use the textbooks of People's Education Society, I suggest you buy the books of People's Education Society. For example, the third year of senior high school is suitable for winning, and the second year and the first year of senior high school are suitable for using biology illustrations and exercises in senior high school, new textbooks and new learning plans, and synchronous analysis and evaluation. These are all very good counseling books, and they are really matched with the textbooks published by People's Education Press. As a student, I suggest you buy "The Victory is in the Hand" and "Biology Illustration and Practice in Senior High School". The former has systematic review, while the latter has the necessary methods and extensions to improve. These are all from the People's Education Society. For the last two books, they are all exercises. You can judge for yourself. That's what I use when teaching my students. Other books, including basic training, are not given to students. Although I have them myself, I am also a reference. We should know that our teachers can selectively judge which topics are in line with the current textbooks. If you buy a book, many of the topics in it are the contents of the old version, then what you do is a waste of time, and it will also dampen your interest in learning if it is too difficult. There are too many study guidance books, most of which have both advantages and disadvantages. If you really want to buy those, I recommend you to buy Document No.1 of College Entrance Examination and Dingjian Learning Plan. "Innovative Design", "Learning to navigate the sea" and "Lightly Winning the Championship" all follow the new textbooks, but the guidance books published by the publishing house are synchronized with the textbooks. You have learned so much, so it's up to you. I also recommend a website for you here. As long as you register, all the contents are free. This website is the result of the joint efforts of Hunan Ministry of Education and teachers. There are many courseware and materials. www.3633.com.cn
