I would have to agree. It is difficult to compare the test results of someone that was at the top of their class 7 yrs ago vs someone that took it last year with a much poorer grade. Perhaps the latter would have the better test results, but not do as well in PA school. I'm sure the faculty is well aware of this. They probably use it as a benchmark for how far back they should allow prerequisites, or also how they might group study partners or emphasize certain material in class.
