Forcing you to upgrade
So I hade two issues with this app. The first thing is the app is not calculating your correct answers correctly. So for example you get a 100% the systems will say you have 4 questions wrong. Secondly I purchased the $49.99 plan for 12 weeks. The app is forcing me to upgrade to the annual plan by literally not allowing me to see the explanation until you sign up for the $99 annual upgrade. I still have 2 months for My subscription. So for these two reasons I would stay away from this app. Because you will have to start all over with another one.
