This is exactly what i was looking for. Something very visual for a visual learner like me. And easy for someone dumb like me. And completely free minus ads. For someone broke like me. The only real problem i have with this app is sometimes the quizes after the text have material that isnt gone over in the text. For instance, road markings 2 only talks about center turn lanes, but the first question i get are about some diamond signal.I recommend this app to anyone needing to learn

Very professional and beneficial! My daughter took her learner’s exam and passed the first time, mostly from studying with this app! Chose the 1 month plan, but she studied hard and we canceled after the 3 day free trial period. There are tons of questions (557) with review sessions evenly spaced to help with retention, and a final exam at the end. Explanations are also given as to WHY the correct answer is correct. Very engaging with lots of information, GIFs, and videos. HIGHLY RECOMMEND!

Yes, my WiFi connection is working. edit: I finally unlocked the chapter, and now I'm at the signs chapter but the pictures won't load. I've been coming back to the app every day ti see if this is fixed, but I'm still not able to load the pictures final??edit: yes, thank you very much everything's fixed now

Before I decided to download this I couldn't pass the permit test to save my life and now I passed! thanks to this but how ever the only downside is that you have to pay to actually use the app but it's not an outrageous price it's fairly reasonable. Definitely will recommend!!!

Never ever again it tryed to kill me


Ngl is working pretty well and the lessons are easy to understand so that’s really nice. I wanna pass the test as soon as I can I swear if after reading the book and using this app I don’t ace that test I’ll cry myself to sleep 😭🙏


I got 22/25, thanks!
