HazMat Test Customer Insights

1. Don't use this to help because it will completely trip you up and teach you wrong!By Studying HazMat material with ad at the bottom of the test is irritating the application with stress standard I don't need you can show these ad when I'm playing a game whatever knot now !!!! please don't do this I will reset the factory and won't give a flying fish about it just push the botton reset everything so please stop the ads I don't need to be associated with them in point and time dam it.congratulations if you found this app before taking the test, you will pass with some practice and reading combination.

2. Thankfully the test is multiple choice! 😎Tricky questions but that's good,tells what you missed after each test can't back up to correct wrong answers till completing each test,study guide may be a little confusing but I really like this,recommended.I haven't done any Hazmat in several years and Let It Drop, and now I'm about to retest for my endorsement.

3. I used only this app and took the pre-test and study guide on the app past at the DMV missing only 2 questions! The questions on this app IS literally the same test provided at the DMV... Download and good luck.

4. there are maybe 3 questions with errors but the test taker should find the answer in the state manual themselves for the source.I DONT test well...i put off taking the real test at the DMV for over a year.

5. I can guarantee that on the test that I took 20% of the questions on the test were not on this app, the practice test or study guide.

6. Y'all keep up the good work on keeping this teaching skill going!MISSOURI EXPERIENCE: I took the test yesterday 2/9/2023 so I can speak from first hand experience.

7. With that being said the other 80% we're word for word the exact same questions which made taking the test a breeze.

8. You will pass on the first try!!As much as I would like to rate this 5 stars for effort I cannot it does not have the correct answers for some of the questions yes a majority is right, but some are wrong and the updated version cdl knowledge should be used instead of this.

9. My wife made me an appointment to test and I put off studying until the night before (not recommended).

10. It's teaching me again to slow down and do it right.As we went through these tests we found many that were wrong or some have 2 answers and they were both right but could only pick one.

11. Despite the missing questions I recommend this app 1000%.
