I was able to start and stop at random. ### 1/5 — Questions are not the same *2025-12-30, version 8.102.10743* I have taken the CDL permit twice now and I have gotten air brakes, and combination all memorized, but when I go to the DOT to take it, it’s not even the same answer, or there was more questions that I’ve never seen before on the test, and not on the app. Look for other apps that have the correct questions that can actually help you, not this app. ### 2/5 — It could be better *2025-06-04, version 8.102.10743* The questions in pool of each subject don’t cover everything on the tests. So far I’ve taken introduction, driving safely, transporting cargo safely, transporting passenger safely, air brakes, and school bus. I’ve noticed in all of the tests, questions that are not in the study pools. ### 1/5 — Do Not Dowload *2025-04-11, version 8.102.10743* Studied for the CDL test using this app and maybe 10% of the questions were actually on the test. If you want to fail your CDL test the first time and waste $6.99 for a subscription that doesn’t help your studying, this is the app to use. Would highly recommend dmv-permit-test.com ### 2/5 — Review *2025-02-13, version 8.102.10743* Need to be able to review all answers missed of the tests you take so you can learn them not reword them. ### 3/5 — Decent but could be a lot better *2023-06-27, version 8.102.10743* I spent a lot of time using the apps sections and testing questions. I got to where I was getting 100% every time. There is a lot of good info here. Unfortunately I failed the exam twice. There were many questions on the exam that never presented in the testing. Why the app is set up this way makes no sense. It’s like they intentionally want to make it harder. I found another app called CDL Test that was more thorough, and I was able to pass on the next attempt. I suggest using multiple resources. ### 1/5 — Bad questions *2022-09-30, version 8.95.10309* Read previous review that questions matched app, that is no longer the case. App will give you a false confidence to go pass the test. The app has limited set of questions and answers. I aced all practices. Limited to 350 questions on app. Drivers station said they pull from 3000 questions at random. Saw questions and answers that were nothing like practice that I for the CDL I was going for had no business studying. Could certainly do more relevant questions that match the subjects chosen to study based off CDL going for with actual test prep. I went in with all the confidence based off of my month of study and constantly passing every practice test, review of sections required for my CDL and continual practice. To failing two of the 4 tests. ### 5/5 — Thumbs up *2022-08-31, version 8.95.10309* Great app highly recommend for studying for your CDL. Passed mine only studying off these. ### 1/5 — Unhelpful *2022-03-24, version 8.55.8591* This app is really time waster don’t used ### 3/5 — Question order *2022-02-01, version 8.55.8591* really like the app just don't like how the answers to questions are in the same order every time, I feel like I'm learning where to find the answer not what it actually says.. ## Frequently asked questions about Official CDL Test Prep ### What does the Official CDL Test Prep: Iowa app do?
