Great app! Really helps and it's not complicated to figure out. But the lending tree ads are making me lose my mind. You can't exit out of it and end up never finding your score. I don't mind ads... they're necessary but if I have to close the app every time lending tree comes up I might as well get a different app

Speaking from my own personal experience, if you're taking the general knowledge, air brakes, or passenger endorsement tests in Florida you'll want to use this app, because the practice mode, and exam mode have the exact same questions as the test, word for word. I can't speak for all the other endorsement tests, just the ones listed on this review. I passed each one of the tests on my first try. I don't think currently that there is a better app in the Play Store that's better than this one.
