Cheng Wei's peak mathematics is really average, and his marketing is very good, but it is also expensive.

To brag, the so-called "paid question and answer group" is just a few seniors in the group answering questions. The method used to solve the problem has nothing to do with Cheng Wei's method, and there is no universal solution at all.

brief introduction

Don't believe those scoring cases in his circle of friends. Those successful cases cannot be called cases at all. Their success does not depend on Cheng Wei. Even if you don't report to class, you still get this score. What you can't see is countless deceived people who spend a lot of time listening to his classes and fall behind in mathematics.

Moreover, the group it pulled you into may not be a new group. The group you entered may be full of people like us, who have finished the college entrance examination, or have finished the college entrance examination. Don't expect anyone inside to answer your math problem. My group is a group of 18, basically all people from the past, and it will be a new group in another year.
