1. 5/5BEST CDL PREP TESTS!!!!

   I never write reviews but I had to this time. I live in South Carolina and wanted to get my CDL class A permit before obviously moving on to my skills test. I was told about this app out of a million other apps. I didn’t buy the SC DMV manual I just used this app. The general knowledge test is the hardest because you got to get 40 or more right out of 50 questions to pass. I studied the general knowledge, combinations and Air brakes from this app and I passed all 3 tests. There’s a few questions from the general knowledge test that weren’t on the app but like 85% were. I guessed on a couple questions. They were worded about the same as the DMV’s questions. I work so I only had a couple hours a day to study. I’m glad I found this app because I didn’t have to waste time with other apps or manuals that have you guessing what’s gonna be on the test. Studying these three tests I just used this app to study a couple hours a day and then on the weekend and that next week I took the tests and passed! Use this app and you will pass.

2. 5/5This is very accurate

   Honestly, I downloaded this app twice in the past and deleted it twice and on the third time I downloaded it. I just took a chance and just took the test and really didn’t know what to expect but I was hoping for the best and the first two tries I got a 70% and then I got a 73%, a bit maybe hour or two to get familiar with the knowledge and then I took the test again and got 80 and then I got 86 so that’s the first test I took after that I was getting and above consistently I think maybe a total of 15 to 20 times and then I went into the DMV on my fourth day of studying with this app and passed my hazmat endorsement. I’m very pleased with this app if I can give you a 10 out of 10, I would because the questions on the test was exactly the same questions that was on the test, maybe 5or 6 questions different.

3. 4/5Some Wrong Answers

   There there are a few questions that you guys have in the exam that are WRONG answers I had to cross check them myself because I knew they were correct from my studies from CDL school and the app said I got them wrong when in fact they were right . Now I AM NOT saying that this app is bad or terrible in any way but these are things that must be fixed within the app . I hope the team can get these questions fixed because THIS IS SUCH A GREAT TOOL but there were multiple questions that I cross checked and the app said they were wrong when indeed they were correct , Many people use apps like this in hopes of getting the proper information they need to pass the CDL exam and start a new career in the trucking field for the most part this is a great tool for anyone trying to get some knowledge on the CDL Exam but is it 100% absolutely correct NO so my advice to anyone using the app is to fact check the questions and write notes to create your own study guide and take multiple different test that are available so you can be assured that you will pass the exam

4. 5/5Go no further!

   Hands down this app was one of the best tools to study for the written test! I decided to get this app because I talked to a few people and they said that this test was fairly difficult and that it took some 2 times to pass. I strongly recommend reading the book first so to better understand everything you need to know because let’s face it this app is what it is a means to test your knowledge. After I went through the book and felt comfortable then I took the test. The nice thing too about the app test questions is that they are verbatim on the state test BUT they wording may be different to trick you so PAY attention and don’t assume you know the answer without reading the full question. Anyways, I passed the test first try and strongly recommend this App to help you prepare. Good luck!

5. 5/5I was skeptical

   Arrived in Missouri for trucking like I’m sure many of you are reading this. Had instructors trash talk this app saying it wasn’t accurate, but lo and behold, I passed with 90% or greater on all four endorsement tests. It works. Make this your Bible and study it until you want to vomit, then study again and you will pass. My only complaint is that there were some questions on the general knowledge portion that were not on this app, but I still managed to pass it with 90% and so should you. The other endorsements were 100% accurate compared to this prep app. Hats off to the app creator, thank you sir. Also, you can skip ads even if there isn’t an X mark in the top right corner by just tapping on it, the ads help make it free for the developer to profit and honestly weren’t too annoying once I figured out how to skip immediately. Good luck!
