Going to start studying for the Commercial written in the next few weeks. For Private and Instrument, I primarily used Gleim test prep book with extra practice tests from Sportys online course. I am planning to follow the same route for Commercial, but had heard that the Commercial question database from FAA was recently updated / refreshed, and that Gleim may now be outdated. Does anyone know if this is the case, and if so, any tips on other study providers? Appreciate views from anyone who may have recently taken the Commercial written. Thanks as always.
