I just took the instrument knowledge test and I received a 78%. Over half of the questions were not in this app. I believe this may have been because the FAA is changing a lot of their questions as of 15 June 2016. ASA did NOT provide any daily, weekly, or even monthly updates to the test bank other than the standard roughly once a year app update. I think they should at least send out bulletin alerts to their customers within the app or email to explain upcoming changes and how this would affect the effectiveness of the test bank provided. Suggestions to make this app better: 1. Offer payment or store credit to customer providing test questions and answers. 2. Update the app, questions or send bulletins at least monthly if there are changes or no changes. 3. The save progress feature either does not work on my iPad or it is very difficult to easily find my left off point. I am using an iPad Mini 4 running iOS 9.3.2
