Just signed up to say... I felt great about the morning, but the afternoon (mechanical fluids/thermal systems) was a bit rough. I was excited to have my cameron hydraulic data book though and pass or not I'll be holding onto it and recommending it in the future. There seemed to be a few I was sure I was doing correct but couldn't get an answer that made sense. Overall I really enjoyed the process, the test, AM specifically was actually fun. I train for physical races a lot and it felt really similar to standing at the start line of a race, and I knew when I opened the book I was prepared. I'll be a little surprised if I fail, but I'm also willing to accept that it's a real possibility.
