Classmate, if you did this set of questions without systematic review, you got 46 points, which proves that you still have some math foundation. After systematic review, your score will be greatly improved.

If you have scored so many points without completely completing the systematic review, try not to affect your mentality because of this. You can consider taking a class or something.

If you get so many points in the systematic review exam, I strongly suggest that you change your major that doesn't take math, or you really don't like your major, and consider other ways of personal development.
