User Reviews
I'm currently working towards getting my permit and was told by my cdl class instructor to use this app as its closely related to the secretary of state test where I'm from. However once I launched and attempted to use the app there is a blue line that blocks all of the questions. I can make out some of them as I can cross reference to other practice tests I've taken. Still would not recommend to anyone who wants to study.
I used thus app along with YouTube to pass all my CDL permit test. I have all the endorsement except for hazmats. I got a new phone and re downloaded this app now there's a blue line running on top of the screen and it's blocking the questions. This app went from a 5 star to 0 because of that blue line.
Not good for mobile phone as the titles cover part or all of the question. Even when rotating the phone you aren't able to see the full question.
might have been a good application but, not compatible with Android 16, on my Samsung s22 Ultra there's a blue line over the questions, all I can really see are the answers.
