I don't know where you are from. If you are in Chengdu, I suggest you buy this book (five-year senior high school entrance examination and three-year simulation). If it is not only the finale of the senior high school entrance examination and the math problem in Chengdu, it should be able to rank in the top ten in the country. This book is all the middle school entrance examination questions in Chengdu, and the middle school entrance examination questions in every place are new questions every year. Only by doing more previous questions, increasing problem-solving skills and solving speed is the key. Huanggang's books are also ok. Because Huanggang was a place where experts from all over the country studied together at that time, the problem was the most difficult in the country, and there were many new problems. In some places, the finale of the senior high school entrance examination is adapted from the above questions, so I recommend "Five-year senior high school entrance examination three-year simulation" and "Huanggang examination paper" (as for the name of Huanggang, I am sorry)
