A college will implement independent enrollment this year, and after discussions in the school, it will give priority to those candidates with a high comprehensive quality, rather than the majority of colleges and universities, based on the test scores of candidates. The most prerequisites for this decision of this college are:. ['Candidates with low comprehensive quality are not good students.', 'The overall quality of each candidate is different.', 'There are feasible methods to judge the comprehensive quality of candidates.', 'Candidates with high scores in written tests are not necessarily good students.']
