I passed my class A with air brakes and combination
Chrisbarras
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.
Fantastic App

It’s a wonderful app! I promise 85% to like 90% of the questions and answers you’ll see on this app will be actually on the DMV Exam. I mean you will pass each and every exam if you study this along with using Quizlet or googling CDL practice tests. I pass four endorsements tests on my CDL along with the general knowledge test all in two days! And I bought this app like two days before I’ve taken the first examination test. Awesome indeed!!!!!!!!🔥🔥🔥

You destroyed your 5 star worthy app
CaptainCr4y83
Im only giving this 2 stars because they destroyed their app recently. I used this app back in February of 2021 to get my class a with all the endorsements and the app was amazing no problems worked great, studied for 3 days and passed first try. Now when im studying the app bugs out, questions wont load or the answers will bug and all of them will be wrong? Whats the point in using the app if you cant learn the right answer or even know the question. Not to mention the number of grammatical errors in a-lot of the questions and answers and the way the answers are set up to be misleading. This app was a 5 star in 2021 best app there was to study now I’d barely give it a 3.

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!
