This is the ultimate preparation,,, I wish I would have been known about this application a long time ago I suggest anyone trying to pass these test to deal with this application only ,,,, I actually had someone try to charge me saying they had the exact text questions but if you pass on here you pass on the dps computer test......................

I just passed my written GK, Air Brakes, and Passenger test here in Alaska. I used this and a couple other apps to study BUT I believe this was the most helpful by a long shot. I'd recommend this App to anyone studying to take their test here in Alaska.

Great app on point with the questions. General knowledge/air brakes/school bus was good but for passenger the questions are not accurate. I highly recommend you skip passenger endorsement for this app.

The reason I said a 3 star rating is because of the ads.Is there anyway the ads can be eliminated.If it do a 5 star I can do.

I would say it is a great app. It helped me to pass my test, including all of my endorsements. However, there are some strange questions that appear during the test day. It would be great if the questions were revised in relation to Californian CDL test questions. Overall, I would give this app 5 stars as it helped me to pass the exam without any exam fail.

It's just awesome! Guys, for the Illinois Hazmat and tankers test, it's almost the exact same questions! I studied the Q and A from the app and also read through the manual, and I didn't get any questions wrong! 100 percent passed! Did Hazmat in about 7 min and tankers in like 5. The app is awesome!! Def study the manual to give yourself the best chance though. Good luck!

It has most of the exact questions that are on today's CDL tests. This is the only practice tool you need. I recommend reading the combination vehicles section as well as whatever endorsements you need, as CV is a little harder to grasp from just the multiple choice questions and I ended up failing my first time testing on that.

It helped me a lot to pass general knowledge, air brakes and combination for class A, the very first time. Also I will always recommend to read the manual. I love this app.

Failed four times before I downloaded this app. After using the practice exams, I passed the first time. 75% of the questions on the real test are here in this app. At least for NY

Wow, I couldn't be more satisfied with an app than this. Everything u need to learn for the test is on this. I literally studied for 30 min on comb, and air brakes and went in the dmv and passed.

Ignoring the part about ads... (WA, Jan 2024) For gen knowledge it was great. I struggled more on the app than I could have ever struggled on this test. For passenger.... what the heck. I was scoring very well on the app repeatedly, but when I went to take the exam I actually failed. Sure, maybe I'm bad... but I had never seen most of the questions before. If you're in my shoes just stick to the book

This used to be a good app but the authors allowed so many unskippable ads on it now that try to install other apps it might as well be ransomware for your phone. Ads happen ever 3-5 questions. Run for 1-2 mins. Jeffrey got super greedy. Do youself a favor and spend 3 bucks on a better app without constant ads. Your not going to get qauilty study time here. Out of the passed 20 mins of using it 15 mins of that is pure ads. I made no purchases the dev responded by trying to gaslight me as well.

Speaking from my own personal experience, if you're taking the general knowledge, air brakes, or passenger endorsement tests in Florida you'll want to use this app, because the practice mode, and exam mode have the exact same questions as the test, word for word. I can't speak for all the other endorsement tests, just the ones listed on this review. I passed each one of the tests on my first try. I don't think currently that there is a better app in the Play Store that's better than this one.

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.

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

This app worked great! I was able to ace all of my tests gen knowledge, air brakes, doubles/triples, tanker and hazmat.. the words may be different from the actual tests on some questions, however one should be more than able to discern which is correct. The ads, understandable.. it's a free app with great information what do you expect.. It's "CDL prep" and does exactly that.
