Best

### ***-- "Too many ads"
I wish there was an option to pay for the app to be ad-free as they are very disruptive while studying.
-- Twelvizm, 2024-12-29

### *---- "Cancellation"
I have been trying to cancel their services for months and have not been able to do so. Unable to reach their customer service for assistance with canceling. Had to block card transactions ( App was very helpful when needed).
-- Outwhitted, 2024-12-29

### ***-- "I’ve pass the first two test."
I failed my air breaks, there where a lot of questions that weren’t on the app. Great for most of the test but some questions are not on the app to study.

### ***** "Preparation"
This app really prep you for the DMV testing. Endorsements are easy to answer & match the study guide. If you study your Manual & practice with this app, it’s no doubt in mind that you won’t pass your Knowledge & Endorsement tests on the first try.

### ***** "Absolutely great application."
Thanks god I found this app again this year. In 2022 I passed my CDL permit through by using this app. Then I was lazy to operate a truck then my permit expired. I found it again and I went through all the questions today now ready to go for my permit test. Just some questions are different but I guarantee you will pass the test.
-- Watan Roshan, 2024-12-23

### ***** "Thank you!"
Studied everyday for 1-2 hours. Questions on the app are almost identical to the ones at the DMV. A few general knowledge questions was not on the app but 80 to 90 percent were. Best app I studied on!
