I was able to use this instead of scrolling Instagram for hours on end. It is definitely worth the price. I ended up passing the ADX exam with an 89, so I was glad I had this to use. ### 5/5 — I passed!!!! *2025-01-27, version 2.2* I used this app to succesfully pass my ADX. I have zero aviation experience and I was able to get all of the information I needed to pass my exam. 100% recommend! ### 4/5 — App UX issues *2024-12-21, version 2.1* No back button when having to view an image or diagram. So I have to exit the test and start over. ### 1/5 — Broken parts *2024-12-07, version 2.1* When I am opening up images on quiz or study mode using my I phone the arrow to go back disappears. Essentially, I cannot look at any charts or graphs provided. Totally broken. ### 5/5 — Thank you Sheffield! *2024-09-14* Thanks to this app, I passed the ADX with ease. The study mode really helps you memorize answers in a flash card style format. The simulated exam mode helped me see what the real exam would be like and it allowed me to see if I’m trending up in my score. Hint: I’d recommend you average between 85-90% on the simulated exam before taking the real one, to practically guarantee a passing score. Thanks again Sheffield for helping me get this useless, but extremely important exam out of the way so I can focus on actually studying to become a dispatcher! ### 5/5 — User friendly *2024-08-20* I appreciate how user friendly this app is! There’s various ways to study in test mode, quiz mode and study mode. If you want to know the “why” study mode is for you. I prefer quiz mode. One of the strategies I used was to take the exam simulator 10+ times and score 80%+ consecutively. The exam log saves your exams so you can review them and learn from them. Great app! ### 5/5 — Great ADX Study Tool *2024-04-01* Love the ease of being able to have it on multiple devices! I use it most on my phone and enjoy being able to study while on the go and at the gym. Thank you Sheffield for creating an ADX study product that we can trust!! ### 5/5 — Fantastic Test Prep App *2024-03-29* This app is amazing! It helped me pass the ADX test. A lot of the questions I studied from the app were on the actual exam. The interface is easy to use, and there are tons of practice questions covering everything I needed to know. I especially loved the study mode feature because it helped me to track my progress and focus on my weak spots. The explanations were great and I appreciated whenever the explanations included statements about what we would realistically come across as a aircraft dispatcher. I would start off with study mode then I would do quizzes on each topic from study mode then move on to test mode. Highly recommend for anyone looking to take the ADX! ### 5/5 — Very convenient app for someone starting out with aircraft dispatcher. *2024-03-17* As someone who didn't have have prior aviation experience coming in, Sheffield's study app is very convenient for someone is just getting started with their dispatching career. Initially after downloading the app, you a prompt a login screen(obviously). At first, I thought I need to have a account by registering their course, but signing up is pretty simple. It is only after you login, and want to access additional study material where you would have reach out to Morris access to additional ADX study material. Just let him know you purchased the study app, and he will grant you access to the materials. While you are studying, the app gives detailed explanation to the answer, and even you initially get an answer wrong, it can guide you to the right one. There were some some concepts that were a bit confusing and so I had to do some internet research to better understand unfamiliar concepts in aviation including any abbreviations that the exam throws at you. I look forward to a dispatching course with Sheffield in the future. ### 5/5 — Great resource!! Main reason I passed the ADX *2023-10-30, version 2.1* This app was a phenomenal resource for studying for the ADX exam. It really helped me prepare, quiz myself, and then practice for the exam itself. I highly recommend this app for anyone that is studying for the ADX. I even was able to take practice quizzes while at the beach with my wife. (I know, what a great way to spend time “relaxing”). Definitely a main reason I passed the ADX exam on the first try. -Pat ## Frequently asked questions about Sheffield School ADX Test Prep ### What does the Sheffield School ADX Test Prep app do?
