Needs Work

Unfortunately this app does not explain why the answer choices are correct or incorrect. I would strongly recommend to the developer collaboration with someone like Gordon West. All of Mr. West's books that I've used so far have not just the questions and correct answers but he explains in detail why the answer choices are correct or incorrect; this ensures not merely rote learning of the answers but comprehension level learning of the concepts underlying each answer, and some may even achieve correlation level learning if they already had some understanding of electromagnetic physics.

I gave this app three stars because all the other basic expectations of an app are met (e.g. correct English, good graphics, legitimate brand etc)

With enough practice on this app it is quite possible to memorize enough answers to pass the test and for some that's good enough. If you take your profession seriously, passing the test should not be enough to satisfy you professional pride and it will certainly not be good enough to do your job well in situations when the skills this test is supposed to examine will matter most.

GROL Test prep

Used this app on my IPhone and IPad to prep for FCC elements 1, 3, and 8. Questions are exactly the same as the test. Testing center only gives a pass/fail grade, but I know I scored in the high 90s as the questions seemed very easy because I had seen them all before. I used Dauntless test prep apps for all 3 of my FAA A&P written exams and private pilot written exam. All have been great apps. Currently using app for my instrument flight prep. The FCC app could use better explanations for wrong answers like the aviation apps have.
