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.

Guide Works

When I set out to obtain my commercial permit I started reading the book, only to figure out that the book was confusing and very time consuming. Guys at work told me to download this app, and when I had down time at work and home I would run through a bank of questions. Within weeks I felt ready to sit for the test. Anyone in PA knows that going to the DMV can be very discouraging by the way they do things. You wait two before your number is called, it’s very frustrating to see people who came in after you being called.
Anyway first try at the test and I passed, overall it took 40 mins from start to finish.
