Isn't this too simple? It looks like a C language test.

1 is divided into four categories according to the average score, and the specific scores are: higher than 90, 90 to 80, 80 to 70, and below 70.

2. According to the average score of the highest score of a single subject (the score of a single subject must be higher than a certain score) and the average score of the lowest score of a single subject, it can be divided into serious partial subjects greater than 1.386, partial subjects from 1.385 to 1.2 and unbiased subjects less than 1.2; Similarly, the average score of the lowest score is 0.857 to 0.75, 0.75 to 0.66, less than 0.66. There are also problems with this model. For example, students who scored 90 points in two exams and 60 points in the other two exams can only be classified as partial subjects and single subjects, and the range method is still limited.

3. Should this award be written in programming language? Didn't you make it clear? One vote veto. A * * * will win five prizes, of course, ranking according to scores is also fair.

4. Disadvantages are A+B A+B+C & gt;; 270 but d
