Great test prep tool!

I would highly recommend this app to anyone studying for the CDL written test!

Recently I was hired to drive school buses in my district. One of the first things I needed to do was pass my written test to get a learners permit for class B with passenger & school bus endorsements. I’ve never been real great at “read the section, take the test” so I looked for practice tests so I’d know what I did / didn’t still need work on and found this app. I used it in the free mode for 4 days, practicing a different section each day, then on the 5th day I reviewed the question bank and took the tests (4 sections: General knowledge, air brakes, passenger safety, and school bus) and passed with flying colors! All 4 sections were passed in under an hour. Out of all the questions combined I think I only ran into 3 questions I opted to skip because I had not practiced them on here, didn’t know the answer, and felt I’d rather skip it than to get it wrong, but overall I knew that I knew my stuff.

Guaranteed Passing Score

I recently concluded my ELDT training course for Hazmat endorsement. While taking the course I needed an app that I could use without having to go online and logging in every time I needed to study. I have a busy work schedule so having an app to easily access was a must for me. This app fit the bill. I studied hard every opportunity I got. I went through all the test phases this app offers for my particular endorsement. Come test day, I got all 30 questions correct. This app definitely help a lot. If you are going through an ELDT training course to get your cdl or adding an endorsement this app will be of great help. Highly recommend this app.

Helped me get my CDL permit in less than a week

This application is amazing for me and I’m glad I found it when I did because I was going crazy trying to study the physical manual, but after just one week with this I passed all three of the tests I needed and am well on my way to getting my full CDL. The repetitive style and explanation after every question not only helps you fully remember what the questions answers are but why they are correct. Would definitely recommend this application to anyone interested in getting their CDL. Will most likely use it in the future if I choose to go after any endorsements.
