I’ll update for anyone who might be interested, but I will say the Sheppard Air program works! The questions on the actual test were basically the exact same. There were one or two questions I had never seen and a couple with slightly different wording but nothing major. Even though it’s basically memorization, I did learn a good bit from just going through all of the questions and reading the explanations. Don’t use Sporty’s or King, in my experience, Gleim and Sheppard have resulted in good scores.
