In the age before time medical schools graded students with the primitive ABCDF system. This was deemed unfair too those receiving poor grades because all medical students are by default solid B+ students. Hence the great powers at the time moved to change the grading system to Pass and Fail and it was good. It was not long however before medical students who excel in complaining changed to system to include an honors grade for those among them who are truly outstanding. Thus the honors, pass, fail system was born. In time those who could not easily achieve honors began to complain that a middle ground must be included and the grade of high pass arrived. The administrative powers eventually moved to include a marginal grade so as to reduce the number of failing students and some such nonsense. Now we live in the enlightened modern age of honors, high pass, pass, marginal and fail. Twas truly a long and epic journey from the vastly inferior ABCDF system and we pray that those days of injustice and woe will never return.
