Have you ever used "Nine Sets of College Entrance Examination Sprint Questionnaires"? How is this book? (Experienced people tell the truth)

I don’t think the nine sets of volumes are credible. I am from Sichuan Province. There is an advertisement for "Nine Sets of Examinations" from a student who was admitted to Peking University: "Before the college entrance examination, I thought there was no problem in taking the second exam, but there is hope for sprinting to Peking University. I used "Nine Sets of Examinations" and the results were I won many of the original questions and ended up getting admitted to Peking University.” Many of our classmates laughed when they saw this advertisement. Because in Sichuan Province, there is a 200-point difference between the admission score for the second line and Peking University. A 9-set test can give a person an extraordinary performance of 150 points. There are two possibilities. This is true. One, the student is a student with special talents in sports. , it is true that students with sports specialties can study at Peking University in the second line. 2. The student is a student from Xinjiang or Tibet, where the first-class score is less than 300. If he is a student from the Tibetan class, he can study at Peking University with a score of 400. In the end, we all regarded this advertisement as a joke

Taking a step back, if this material was really good, would we have never heard of it? If this material sells well, will we still buy teaching aids such as "May 3rd" and "Century Gold List"? If this material sells well, will the publisher not have the funds to carry out large-scale publicity, and will it only advertise in the gaps between English tutoring?

So students, I personally think there is no need for you to waste money on buying such anonymous teaching aids. Moreover, according to friends who actually bought the "Nine Sets of Volumes", the paper in the "Nine Sets of Volumes" is rough, the answers are worn out, and many questions only have answers without detailed explanations.
