Horrible payment method , not details in subscription.I was willing to buy 3 month plus , but I was forced to get 3 days free , after that service was cut . Update: After trying too many times ,I did get the service 3 months. This app is the best!!! Passed my exams first try, 100 %,correct( from Florida). The payment method still inefficient.

10/10 Thankful for having the chance to learn through this. I passed my permit test from just studying the app the whole week. I loved it because it's great for auditory and visual learners. One of the major features is that every lesson theirs a video on a teacher breaking every lesson down for you, and afterwards you take a test. download it now, and forget the dmv book. Oh and the pay is totally worth it

I'm giving it 5 Star ist a great way to learn but the down side is if you want to continue you have to pay for an subscription it's 5 question after that if you want to continue you have to pay I don't like that I'm trying to learn not waste money

This app would be perfect if only I could watch the videos in 1.5x or 2x. My ADHD is suffering
