I went over 500+ questions on the app. There were several questions on the test that I never saw on CDL Study Buddy and there were several questions that had the wrong answers in the app. Don’t let this be the only app you use to study with. ### 1/5 — Trash *2019-06-18* Trash ### 1/5 — Keep crashing *2019-03-10* I like the app but I have to delete it do to it keep crashing ### 1/5 — No good *2017-08-13* Crap can't get to the audio that is what I need , to hell with your practice test ### 1/5 — Not up to date on your manuals *2017-06-02* I'm a manager at a CDL test site in Indiana. Very nice app, but you need to make sure all your manuals are up to date. The Indiana manual is not. If they give me the 4 point brake check in the old manual that you provide they will fail their air brake test ### 1/5 — No dice *2017-01-02* Not many questions from the app on the the actual test. Maybe a handful of questions out of the 100+ over 4 sections were on the test. Many of them were not even close. Uninstalled. Would not advise using this app ### 3/5 — Great Content !! Too Many Ads *2019-06-05* This has great practice questions and it’s helped me a lot, however there are WAY too many ads which is distracting. It also freezes half way through the middle and I have to restart the practice tests over again. If they could get rid of the ads, fix the glitches and add video content for CMV Pre-Inspection practice test, I will give this app 5 stars ### 5/5 — Study buddy app. *2019-05-07* Works great for me. Ads are annoying but hey it’s free and for me was an excellent means of tracking my progress! Obviously you still have to study but since you can measure your progress so easily it builds confidence in your ability to pass the necessary tests. ### 5/5 — CDL A permit *2018-08-27* Passed general , air, combo, double & trip. Thanks to this app. Most all the question on my exam were on this practice test. Location MASS. AND it’s free ### 5/5 — Want let me do any practice test *2017-08-14* I had been studying every since June 2017 and every time I went to take the test I failed it went back last week and I passed passenger and school bus now I have to get general knowledge and air brakes done. But for some reason I can't get the app to let me get to the practice test ## Most praised reviews (6 highest-rated) ### 5/5 — Let's just say I pasted everything today !!!!! *2017-07-18* Using this application helped major time, I'm in California Oakland. I have been studying for like two months. I used this app and all its features. As well read the commercial handbook 2017 and past all my endorsements. ### 5/5 — Cdl A *2017-02-11* Studied the app and the hand book for over a month and the first time I took the general knowledge I missed it by one and failed so continued to study the app and I passed my general knowledge air brakes combo doubles and triples tankers and hazmat all in the same day. This app is the best and the general knowledge test was the hardest of them all. ### 5/5 — Spot on! *2016-10-29* Needed to get my class B and this app was perfect. Everything you need to pass general knowledge, air brakes, and pre trip, is right here in the tests! I would do a 50 question test, 4 times a day , for a week, and passed easily! Thanks again for the great app! ### 5/5 — Great app *2016-10-20* Just took my class A test at the DMV and passed. I used this app to study general knowledge, combination vehicles, and air brakes for the past two weeks. I passed with the first try! 10/20/16 James S. ### 5/5 — Already Class A Driver *2016-04-15* Thank you for this is perfect and with audio section . I am studying HazMat .
