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. 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

3. 5/5Thank you Thank you Thank you !!!!!

   Read the Questions STUDY the ANSWERS, cdl prep tells you why the question is wrong and pulls a segment from the book to go over , you can pull out your manual read the statement for yourself or real it off your screen either or CDL PREP has no videos no fine line of information thats going to jump out at you , you have to read and study the questions and why your answers are wrong , the DMV questions are the same if not VERY VERY SIMILAR to every question asked on cdl prep , just study the information and why you got the question wrong i learned more off cdl prep that i wouldve reading the entire book front to back THANN YOU CDL PREP for helping me began my journey to financial freedom i passed my General knowledge 100% , Air breaks 95% & Combinations 94% on my first try all flying colors because of you i am so fortunate to have been granted with this app THANK YOU THANK YOU THANK YOU!!!!!

4. 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.

5. 5/5Great app. 2023

   Hi… I wasn’t how true this app was when it came to testing and studying the book but, after studying the book and the app for most part is pretty much the same question. After passing my first test I’ve put my trust in the app for every test after my (doubles/triples) test. I didn’t read the book once I passed with just studying the app. The only test that gave me a issue was my hazmat test. I would definitely recommend reading the book for that part. That took me to my 3rd try to pass. This app for (hazmat) doesn’t have all the updated questions. But speaking for every other endorsement I only used the app and passed everyone under 2mins. However, everyone is different. Thank you for the app. It only took me 3 weeks to get my permit and all my endorsements from just studying the app. Good luck everyone ✊🏽
