James, I set out to do a 200 question test the weekend before I took the test, but I only got 150 questions in before I had to stop and get back to Mom life. I didn't do well....got a 56. I was very discouraged after that test, but it was good to see where was struggling. I used the last 5 days after that test to focus on my trouble areas. The test I had taken was the Andy Crow online simulator and it was very true to the actual test. Very wordy questions with at least 2 correct answers. They expect you to choose the BEST answer out of the 2+ correct ones. I ended up memorizing the knowledge area chart and really didn't reference it too much. Definitely have the formulas memorized, but otherwise, it's a lot of situational questions where you have to think through what is the best thing to do. Good luck.
