Passed ADX because of this app

Best decision I made was to download this app. I had very minimal aviation experience prior to beginning studying. After 2 months of using this app, passed the ADX knowledge exam with a 90%. Would have never passed it if it were not for this app.

There is a ton of information within the app, but is laid out nicely and makes studying a breeze. They provide reasons and references for their answers. They also provide videos on how to calculate many of the performance calculations.

I wanted to throw in a little thank you to Sheffield for providing this app to use for studying. Made the test a breeze because of it!

Excellent !

Sheffield ADX Prep is the BEST, most efficient and thorough way to study for the ADX Dispatch Exam. I used Sheffield ADX Prep and ATP Prepare to prepare for my ADX Dispatch Exam and the ATP Prepare didn't explain ANY of the mathematical equations, which led me to the Sheffield ADX Prep App. The Sheffield ADX Prep App includes outstanding videos which breakdown and dissect each equation making each easy to understand. Definitely recommend !

Great ADX Prep app!

New Sheffield School of Aeronautics' "FAA ADX Exam Pre" has clear screen layouts and is much easier to use. My study efficiency was going up.

Technical service staff was always quick to respond to my questions. So I didn't waste my study time.

I've learned how to budget my test time using the "Exam simulator mode." They really know about the real world of ADX. (This is obvious if you check the school history)

I strongly recommend the "Sheffield School of Aeronautics - FAA ADX Exam Pre."
It helps you succeed in the knowledge Test.

I passed the ADX Knowledge Test on the first try.
Thanks Eric for the great study app!
