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

The ui is a bit clunky but it out did my expectations having all the manuals in the app and all of the endorsements. The questions were like word for word lol. I passed container ,general knowledge, airbrakes, doubles&triples, and tanker first try. But I've had experience as a diesel mechanic so that helped a little. Thank you for the app. Edit: I will add you definitely should study the manual for doubles and triples. I barely passed that one.

This app is awesome! I have been using it for a couple weeks now after studying my manual for over a month. I took my written today and PASSED! School and Passenger endorsements and general knowledge. Just about every question I had was in this app. I found practice mode very helpful cause you can go through every question. If you want to pass, this app definitely helps 100%
