I took my ADX exam today and passed with a 91 using just Sheppard Air. I memorized their sheet(s) but improvised slightly. I ended up only getting like 3-4 questions off of the entire memory sheet but in general everything else was close to their question bank so I was well prepared and done in a little over an hour. I spent the prior 3 weeks on it almost every day learning(and relearning) material but I do have an aviation background which helped a great deal. I wanted to knock the exam out ahead of time so I can put more energy into preparing for the oral/practical during class. I start school this coming Monday at Aircraft Dispatcher Training Center in Farmers Branch, TX.
