CDL Study Customer Insights

1. This app is garbage use CDL PREP instead it's almost verbatim on BMV\DMVApp is buggy, marks correct answers incorrect (while providing information that clearly shows my answer was correct), randomly changes language between questions.

2. Please use all resources available to you to pass your CDL exam because this app alone is somewhat helpful but not guaranteed.DO NOT USE! Not only are some of the answers it says is correct, but it also on the hard version of the exam gave me 4 questions in Spanish and 56 in english... I don't speak Spanish.

3. great app you should get this appThis app is okay for some use but it contain a lot of errors such as giving you the wrong answer, some misspelled words in the questions, and several questions asked in another language that's not beneficial if you only speak English.

4. i really like how on multiple choice test questions ,, ,, you think ok ,, im pretty sure that one is the right ansure and then imediatly after you get to find out if you got it right or wrong and right then when you find out they always have a short or long paragraph explaining why very detailed explanation of proper truckdriving procedure .

5. you can study how many times you want and the questions are very clear to practice your knowledge test.great study tool .

6. Everytime I take an exam it starts going bilingual and marking my correct answers incorrect.

7. The only issue I have is that some of the "correct" answers on some of the quizzes are wrong.

8. I do, however, like that the quizzes give you the explanation for the actual correct answer at the bottom of the screen.excellent app for cdl a students.

9. Yes I have ensured I selected English and I confirmed the answers in the study portion and the book.

10. Questions will be repeateded 3 to 4x in the same practice test.
