“I have studied and praticed all test for general knowledge combination and airbrakes ready to take my test is there a high percentage that i will pass, there are so many apps out there but i must say in my class the other day they showed the same exact question and answers ive been studying on a video i was answering them before they gave the option to pick ABC i m ready to take my test but cant give rating until i know it was useful Percent on passing by using this app? Will update with test results.”

“I had been told by several drivers, including my boyfriend not to be disappointed if i didn't pass my written exam the 1st try. Well, I surprised even myself and did pass! I've been riding with my boyfriend for 3 yrs, but this really helped prepare me for the testing. I recommend that you use this as a supplement not a replacement to reading your state's CDL handbook. (Which btw is easily accessible in this app too!) I'm now studying pre-trip and videos to prepare for road test. Thanks study buddy!”

“Great application, very helpful. Must have been made by an experienced driver and not just some college idiot. However, a question in the General Knowledge practice test seems to be broken. "Which of the following statements about your mirrors is true?" The correct answer has been set as incorrect, along with every other possible answer! Not a big deal, but that's what reviews are for! 5 Stars when resolved, of course.”

“I passed my written test today!! I got every question correct! I failed it the first time without studying. (I had been away for 6 years, and let my licence expire; so it was required that I take the written and driving test all over again). Thank you for a great app. The information is given in a manner that helps you retain it. I spent only an hour on it. I also prayed hard! Thank You, God, too!”

“Needs a tweek in a question or two... "which of the following are true about mirrors" apparently none... lol kept telling me my answer was incorrect. Even after answering it several times each with a different answer. I am using this app as a study tool for the Massachusetts CDL test. Thank you JackzAppz...... greatly appriciated. Hope this Boston Chick passed. ♡♡”

“When I started working for the state Highway department I already had a class B CDL but in order for me to move up in pay scale I need to get my class A. I took my combination test and got 20 out of 20 questions right studying with this app. I just have to freshen up on my trailer skills to pass the driving test.”
