I can only speak of the California CDL permit test… this is THE best app you can use. I tried another free app but it was very limited and didn’t have the same format. The way they repeat your wrong answers 2 more times before you can move on is very helpful. Repetition is key. They also repeat some of the questions from one section to to the next. They are all mixed up which makes it helpful. I took my written test today with my passenger endorsement and general knowledge and passed. There was only a couple questions that I didn’t come across in this app but all the other questions were exact and even written word for word. I answered very fast because I recognized the questions before I even finished reading it. I used the free app and there are ads, and they are annoying, but it’s a free app so stop complaining. The ads only pop up when you have either closed out the app and restarted the questions or between exercises. If you don’t like the loud ads, turn down the volume on your phone. Great job and making a useful and accurate study guide. My hat off to you. 🧢 Thank you.

I started using this app about 2 weeks ago at the recommendation of my CDL instructor. I’m preparing to get my CLP before class and so far I have passed Air Brakes (90%) and Combination Vehicle (100%) and Doubles/Triples (100%). My method has been to read through the state manual for the specific section once, do all practice sections in the app, read through the manual once more, than take a practice exams in the app. Upon scoring above 90%, I go to the DMV and take the knowledge test for the subject I’ve been studying. At least for my state, the questions have accurately represented the test from the DMV.

There is no other CDL prep test to download but this one. It’s spot on at least for the Pennsylvania one never snooped around other states exactly how is on the actual test is how it’s on here maybe a few words moved around other that it’s spot on. I never studied the manual nothing just kept testing myself over am over hundreds of times before I took my permit test passed all three in one shot went to school got my CDL. This is free compared to others you have to pay for an aren’t even real questions on the real test.
