我个人认为，这里的A B C D 是属于评分等级，应该表达为grading. 翻译如下：The graduation score and computer score rank four gadings, which are A B C and D. 下面的例句你可以参考一下。When Einstein was in school, the grading system ranked students on a scale from one to six, with one being the highest score and six being the lowest.当爱因斯坦在学习读书的时候，评级制度将学生从一到六分为六个等级，一是最高分，六是最低分.

There are four stages A B C and D of The Graduation Score and The Computer Score.
