I passed my class A with air brakes and combination

I was able to pass the general knowledge, air brakes and combination thanks to this app. I did have to retake the air brakes portion one time but that’s due to me rushing it. Other than that every question I saw on here was on the test in some variation so as long as you know every question and answer on here and read your state manual you honestly can’t fail. I did every test and made sure I got a 100 before I retook the test and also read the manual. And pay attention to the little things in the manual because I think they are trying to make sure your awake by the way they are wording some of the questions.

Congratulations Chris! We are so happy for you.

Love it!

Have nothing but good things to say about the app; if you don’t pass your test with this app, it’s because you didn’t study and prepare for it. I misses 2 questions out of the 50 on the general knowledge and was 100% on hazmat as well as combination vehicles and air brakes.

Do not rush it, take your time and. Are sure you UNDERSTAND the material; if all you do is memorize then you will fail.

I have tried all the apps and this one is without a doubt the best!

Developer Response ,

Helped me pass!

Thank you for this app. I was able to pass both my Hazmat and Tanker endorsements I need for my new job. There were just a couple questions that I had that were not in the app but with common sense and these practice tests I was able to pass. Thank you again.

Developer Response ,

Thank you! Congratulations on passing and we are glad to have helped!
