I took the Private Pilot Helicopter (PRH) exam in September, 2023. In my opinion, as long as you dedicate sufficient time and follow the advice/counsel contained within the King School preparatory videos, you will easily pass the test itself (i.e., you will score much higher than the required 70%). Once I had completed all instructional videos and covered all the questions, I took 3 practice exams and felt comfortable scheduling the test. I arranged to take it about ten days later at a nearby facility. Over the next ten days I took roughly one random practice exam each day and never scored lower than 95%. On the exam itself, I scored a 97% (missed two questions) with almost an hour to spare. My experience suggests that a handful of the exam questions are indeed re-formatted/re-written (but not many). I was only disappointed in the fact that I didn't get 100% and thus a King School Ace hat!
