It breaks my brain that repeat pass rates are lower than first-time pass rates
I'm an Industrial and Operations Engineer (University of Michigan, Class of 1997 - Go Blue!) I am also an educator. I have been helping people pass standardized exams for 20 years now, including individuals taking the PE.
I wrote a piece about a couple of the "hidden" reasons an engineer might fail the PE exam: how your nervous system reacts under pressure and the test-taking strategies nobody teaches us.
Repeat pass rates are lower than first-time pass rates.
Civil Structural is 58% first-time, 37% repeat. Civil Construction is 56%, then 36%. Electrical Power is 57%, then 39%.
People who failed and studied harder are passing at lower rates than those taking it for the first time. If studying more was the answer, that pattern would be reversed.
