I'm signed up to take the PTOE exam in a week or two. I know that the test was revamped to make it more difficult. Does anyone who has taken it recently have any tips on what to study. I'm reviewing the latest refresher course but I'm hearing that I'm expected to know various formulas and components that aren't covered in the course. This test definitely extends outside my current field and I'm concerned that I don't know enough outside of my knowledge base (Traffic Signals, Signing, Marking, MOT, Ped/Bike facilities). Any advice?
