Some 5,780,000 people who had reached college age within the last decade, many of whom were still working in the countryside, took the test that fall, but there were then only 273,000 slots at the universities. In 1977 and 1978, then, only some 5.8 percent of those who took the examinations could actually be enrolled.61 For the first time since the Communists ruled China, class background was not a factor in selecting those to be admitted to university. Enrollment was entirely based on merit as measured by examination scores.
