Freshly out of disastrous PE exam, I thought I'd analyze "CUT SCORE" hydrologically and share with you all.
Here's how I analyzed "CUT SCORE."
I used SCS Unit Hydrographs' time ratios, discharge ratios, and mass curve ratios to come up with a cut score with a few assumptions. I scaled 80 questions to the time ratios, and plotted the discharge ratios and mass curve against it. Remember, an UH is a nice "bell-shaped" curve. The mass curve intersects the UH exactly at 0.7. I assumed this intersection's UH ratio as NCEES's cut score of 70. I also assumed that the area under mass curve beyond the intersection is a "PASS ZONE" and the area beneath the intersection point a "FAIL ZONE."
The total number of questions needed to be answered correctly in order to fall in the "PASS ZONE" is, hydrologically, 56.
In order to pass the PE, you must atleast score 56/80. I proved it hydrologically!!!
Make no mistake, when you say a scaled score of 70, in fact, it is 70%.
You think I am insane? so be it.
