Seems like i finally found an app that actually ask questions from the cdl book. I’ve been taking practice test from other online platforms and was thinking i was going to straight pass the test with ease.

Well when i took the hazmat test, the question never revolved around anything that I practiced for and i wasted $100 dollars thinking eventually they would give me questions that matched up to what I practiced. Nope lol. People at the dmv gave me the book. Then told me to leave online stuff alone cause none of the material on the net is on the test. Everything in this book is what you get tested on.

I then also went and compared what i was practicing to what’s in the book. Sure enough nothing on the practice test was in the book😅 This app though is way more accurate to the book though. Probably not fully accurate but it’s a good amount of stuff here that you can find answers in the book. Give it a shot

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.

Was 99% verbatim accurate to my actual tests

I went from 0 knowledge to passing my air brakes and combination tests in 24 hours. Had my general knowledge down in a similar time frame. I didn’t even have to open my CMV handbook, this app covered every single thing. It is as close to cheating as you can legally get; it’s amazing and the best $10 I’ve spent.

All i did was go through each lesson plan when i had downtime, anything that wasn’t obvious to an outsider i didn’t know. Learning from mistakes, i just finished each section one after the other and by the time i had finished all sections, i was able to get at least a 90% on the first 3 practice exams. If I had more time I would have done more practice tests, but turns out 3 was enough! With that method, i passed the test for my Air Brakes, Combination, and General Knowledge all in one sitting with ease.
