If wikis were enough, the information asymmetry would not exist unless these people were unaware of wikis and other sources of information like textbooks, which I find unlikely.
Wikis are enough. They are just not enough to ace testing. The goal of testing here is not to check if a person knows/can do a thing. It's a gatekeeping mechanism to filter out people from entering a course/university.
Eventually this is a lazy mechanism to select prospective students to a course. The purpose of the course is to prepare people to build an air plane or be a good doctor, historian, architect, journalist or whatever. Not be good at exams and interviews.
When you make testing all about gatekeeping, wikis don't help, because the questions are not about test of knowledge of skill.
If you have a pervasive cram school culture in your country, eventually you have to import/buy from other people because your people are considered on-paper geniuses but are not good at any thing apart from acing testing.
I guess for where China stands now. Making chips, airplanes and space stations needs the real engineers not just the ones who can score well in exams.
