You just need to write a sincere letter to explain and let the university re-examine. If you really want to go to this university, you can ask the school if it is possible to transfer to other related majors.

The grade will not be re-graded, and each question will not be re-evaluated according to the standard score. But every year, some students still use grade review to get their scores. If you think your grades and estimated scores are too low, I suggest you apply for a grade review.
