Prior to 1993, students needed to choose among two university entrance examinations, the HKALE or the Hong Kong Higher Level Examination. The former originally led to a three-year course in the University of Hong Kong (HKU) at the end of Form Seven (Upper Six), mainly for students in English-medium schools. The latter led to a four-year course in the Chinese University of Hong Kong (CUHK), then operated in Chinese, at the end of Form Six (Lower Six) for students in Chinese-medium schools.
