The app was great. Easy to follow, learn and progress. The app has all you need to successfully pass a theory test and when you log on to DrivingTheory4All website you can access the hazard perception training. I passed both parts of the theory/hazard perception test 1st time with a very high score. If you follow the app training method you are guaranteed to pass or your money back. The only reason I rate the app at 4 stars and not 5 is that during the DVSA test I encountered several questions that I had never seen before that were certainty not within the app. It could have been the difference between a pass and a fail but fortunately not. I passed and if you buy this app and follow the training, so will you.
