I think it's true. I am a sophomore. Before signing up, I looked up a lot of their information on the Internet and saw an official WeChat account named Xue Kui List Education. The official read the profile of each teacher, and the student ID cards displayed are all true. This can't be fake. I signed up for a math class and got 68 points in the final exam last semester. Now my monthly exam is basically stable at around 105, and I feel quite good about myself. It doesn't matter whether I am from Tsinghua Peking University or not. I would appreciate it if you could take my answer. If you need anything else, you can ask, thank you!
