The reason was very simple. They had heard that the college entrance examination papers would test the students on much more complex knowledge than what they learned in school. This was because the newly resumed college entrance examination was for the entire country. As long as one wanted to go to university, one could register for the examination. However, the number of people who could be admitted to each university was very few. If there were 500,000 people who took the college entrance examination, not more than 20,000 people would be able to enter university at the end.
Sixth High wanted to get first place in the rankings once the college entrance examination resumed. The local top scorer of the college entrance examination must be from their school. This represented the dignity and status of Sixth High!
