CDL Prep Test - 2024 4+

I used the app provided by my state dot (Iowa), paid their premium fee and studied like crazy, getting all correct many times on all the practices tests and covering all material, yet when I took the exam there were many many questions I was never presented in the prep.

This app however seemed to cover all of them, after trying this resource I passed on the next attempt.
The feature to flag question that you need to review and present them on their own is a great feature. I failed twice before this app and nailed it after using this tool once…and aside from some ads, it was free.
My only complaint was a few questions that included fractions in the answers were presented in time and date formula which does not make sense. It was easy to provide feedback on those Ana I hope they get updated soon.

I am preparing for the Hazmat & Tankers endorsements. I have tried several apps. This one is the most thorough & helpful with the ability to “star” a question. This feature helped me correct questions I kept getting wrong. I also appreciate the info below the answers that explain the topic whether or not I get question right or wrong. Most apps only give info when you get it wrong. Having the info available, and reading through it, helped me to steadily increase scores.

You can study it through the app for free & memories the answers pay $15 or $20 at the DMV if you pass you'll save yourself $5,000 or $6500 because that's how much it costs to go to the diesel driving academy school & just because you go to school it's not guaranteed you will pass because when the test is sitting in front of you, you're on your own. So either way, you still have to apply yourself..........either way.
