Wang Houxiong has a complete understanding of textbooks. This book is very detailed and the examples are classic. I use it in every subject. You can use the top math students' question bank to expand your ability and thinking. As for English, grammar is not the most important thing. After all, there is only one point in a single choice. You should buy an English reading week plan and train yourself in reading comprehension and cloze every day, which is not only helpful to junior high school, but also beneficial to senior high school. If you want to buy a grammar book, you can buy a five-year senior high school entrance examination and a three-year simulation.
