National Higher Education Entrance Examination
The C9 members' undergraduate program is highly competitive. Five of the C9 members, namely Tsinghua University, Peking University, Zhejiang University, Fudan University, and Shanghai Jiao Tong University, are the hardest for students to get in. Only less than 0.2% of National Higher Education Entrance Examination ("Gaokao") takers get admitted every year (as a comparison to 0.6% of SAT-takers accepted in the five most selective Ivy League schools in 2012).
