The difference between college entrance examination and independent enrollment
Compared with independent enrollment, the college entrance examination is very exam-oriented. Therefore, the college entrance examination takes care of the disadvantaged groups far more than independent enrollment (only relative. The college entrance examination itself is still a vulnerable group, but it is not as weak as independent enrollment. Although from the perspective of the whole society, autonomy has improved the quality of college students, but this improvement is at the expense of the disadvantaged groups to change their destiny through education. This is a major drawback.
Disadvantages of self-enrollment
Another drawback is that the "autonomy" of independent enrollment inherently excludes supervision. Therefore, it is possible that enrollment corruption will be much more serious than the college entrance examination.
