## Main Question or Discussion Point

I am an instructor in a DOD academy. I am trying to show that the way that students are being graded in a particular performance test is a statistical improbability.

I have 200 students, all of which recieved a final grade of A in a course which consisted of 38 performance tests. These students consisted of 6 different classes which conducted these tests.

the academy works fon a graduate level 10 point grading system, i.e. 100-90 =A, 89-80 = B, 79-70 =C, 69 and below failure.

My logic tells me that it is impossible for 200 human beings with varying intelligence levels, all to recieve the grade of A for 38 individual performance tests.

I may not be providing sufficient amount of information, but if anyone out there can help, it would greatly appreciated.

Thanks in advance to all!
