Regarding the triage of freshmen in Shanghai University, how to calculate that the college entrance examination score accounts for 45%? Is the difference between 60 points and 62 points after normalization far? Classmate ~ this is still different. If you major in science and engineering, because there are many people in science and engineering, the difference of one point may be the difference of several hundred people. So 62 to 60 still has certain advantages. Other categories, although few people, are different. Moreover, the normalized score of the college entrance examination accounts for 45%, so don't worry too much ~ there are also scores of GPA and comprehensive democratic evaluation ~
