If the math score is below 40, it can be roughly divided into two types of students. The first is the students who get poor grades in mathematics because of extreme liberalism, and the second is the students who get poor grades in every subject. These two kinds of students have a * * * nature, that is, there is no way of thinking in science, or even nothing. 40 points in mathematics is one-third of the test paper, and even half of the test paper can't be reached.
