考试评分采用5分制，且容错率较高(如统计学考到70-100分的范围内，最终成绩都是5分），通常3分被认为及格。需要注意的是，一般的大学大概3分就可以换学分，但是顶级的大学至少需要4分，甚至大多都需要5分。

The exam is graded on a 5-point scale with a relatively high tolerance for error (for example, in statistics, a score of 70-100 will still result in a 5). A score of 3 is generally considered passing. It's important to note that while most universities accept 3 points for credit, top universities require at least 4 points, and often 5.
