No, when college students ask for a review of their grades, the school will recalculate and accumulate the students' grades to ensure that there is no deviation in the total score. Every question the students do will also be re-examined. If each topic is reviewed and re-reviewed, it will be slightly different from the total score before the review, and the total score will change, but it is rare to find it lower and lower. In short, most of the grades will not get lower and lower, and the grades are basically the same as before review. Unless the system adds the wrong total score or registration error, this situation will be higher and higher. If students suspect that their grades have a big deviation from the estimated scores, they can apply for a review of their scores in this case to untie themselves and their parents.
