The Sheffield ADX app does not disappoint!

The Sheffield ADX Prep App is an intuitive and versatile tool, that is built to meet any student at their level of ADX-educational need. In terms of written-resources, I called on no other resource; spiritually, I had to go to the throne of Grace...but I digress.

•The Study feature is tailored to the student who cannot learn without knowing the “why” behind the answers; great for tying other facets of the Dispatcher world together
•The Quiz feature, in my opinion, is the most critical feature in this app, because it gives you the fastest feedback (right or wrong), and allows you to cover a lot of ground in a relatively short amount of time
•The Test feature gets you in the habit of knowing what you know; it allows you to go through sections of information, but does not give you the results until the test is complete
*BONUS: Your Test results are automatically saved allowing you to go back and review areas of strength and weakness
•The Exam Simulator gets you pumped for the real deal! Pulling 80 questions at random from all sections of dispatch study, you get the same amount of time (programmable timer) you would get in the Lasergrade Testing Center

As long as you are willing to put in the time, and you can keep your spirit intact, this app can and will give you the knowledge you need to get the job done, and get the results you are after.

Very Useful App to Pass ADX exam!

This app made studying for the ADX exam a lot easier. As someone with little knowledge of where to even begin in regards to this exam, this app helped me to create a study plan that was realistic and fundamental to putting me on the right path. I was able to pass the exam within a few months of studying (starting from ground zero).

The app has a ton of useful information and tips on how to correctly study and analyze the information in order to prepare yourself mentally for the test. The test mode feature on the app allowed me to gauge my progress and inform me of weak areas. I also utilized Sheffield’s online resources - which they will provide to you after your purchase the app - which was a good way to see the information presented in a new light.

If you’re serious about passing the ADX, this app is worth every penny. Put in the time and you will pass!

Extremely Helpful!

A very useful app from the top training institution in the business. I have already taken and passed the ATP written (the ADX test is very similar) so take my word for it, this type of clean interface is what you need to memorize the entire 1500 question dataset.

Study function is great for unfamiliar concepts and the Quiz function is very helpful for repetitive memorization of the general knowledge questions. Also has Test and Exam functions which are helpful for ensuring you can answer a varied 80 question exam in the allowed time. Some functionality is not available without being enrolled in a Sheffield ADX class, but the app is still perfectly usable without the back end resources.

Good luck. Give yourself enough time and get a well designed study aid like this app and you’ll do fine!
