代码解释：先设置变量value1，value2，value3，分别为每次考试的成绩，然后在一个大的whlie循环内进行if判断，如果考试结束，也就是id=540,那么开始执行，进行评分算法从而改变value1/2/3的值，如果value1/2/3的值为3则表示优秀，2则表示合格，1则表示异常。最后进行总的成绩判断，也就是取value1/2/3里的最值，作为最好成绩，然后录入数据库。
评分算法：180个数据，如果呈现递减且无异常数据（x<2或x>100000）则为优秀，将对应的value值设为3，如果满足递减或无异常数据（2<x<100000）中一项则为合格,将对应的value值设为2,如果都不满足则为异常，将对应的value值设为1
