Taiwan and Korea have even "fairer" systems. In China different provinces got different test problems. Especially students from Beijing, Shanghai and Tianjin get completely different ones. In Taiwan/Korea everyone takes the exact same test.

However I've never met anyone from these countries who have a high opinion of their systems. Personally I do think our standardized exams cause massive 'overfitting' issue (borrowed from machine learning). The exam is not as brutal as Korean one though.

YMMV.
