I think a key point that may have been missed is that it is not worded as an "a or b or c", etc., it would be ALL of the above as I read it.
I attempted to get mine in Washington state 20+ years ago. At that time because my degree was a BS-EET, not BS-EE, I needed letters of recommendation from three existing PEs. I could only get one to write me that letter, so I never even got the chance to try. Maybe it's different now, charlie b, do you know?
One guy I went to school with (who did get a BS-EE and EIT) took it 4 times over 10 years and failed. I'm not sure if he ever tried again, he had his own successful System Integration business by then and decided he didn't need it any more because he could just hire PEs. He of course did a lot of control work, but he said part of the testing was on HV distribution and such, which he had no interest in. That's the part he could never get past. He would never need to use it, but the exam process was blind to that.
