You can learn from Sheppard. I don't understand this argument. After using Gleim or most study prep softwares you REALLY won't learn anything. Literally Gleim has explanations "Answer A is incorrect because the correct is B" wtf?
God forbid one should look up the *reasons* A is incorrect.
The explanations Sheppard has is great with amazing references from books I've never heard of. Now the preferred study method Sheppard has you won't learn much, just memorize. You don't have to use that study method and you can do it old fashioned and learn every question if you have the time.
Sheppard simply cites the relevant section from the particular FAA publication. They will add their color commentary on a question if they feel it is relevant. So does Dauntless, and in the same way. Books you've never heard of? I've never, ever seen a citation in Sheppard that wasn't an FAA publication. These are the same people who encourage you to try and memorize unfamiliar questions after a test and call or email them after your test to ensure they get it into the study curriculum.
I've used both Dauntless and Sheppard, by the way. Sheppard gets one tiny edge for setting up a study process that Dauntless doesn't, but that process can be applied to both. Dauntless has a superior user interface and better flexibility on how you use their software. Sheppard has some silly ideas about how people use software, in my opinion.
Also, I don't know why people are so defensive to learn these written questions. I know they're trying to improve these writtens to make them better and more realistic but I haven't seen it. Just pay your money, take the test and call it a day. I don't think those tests make you any better of a pilot by learning the FAA tricks on cross country planning or Microwave Landing Systems.
This is a matter of debate, in my opinion, best left to FSDOs and DPEs. It's stuff we need to learn one way or another. The
validity of the subject matter is up to those guys.
@drunkenbeagle made the most salient point - if you study the FAA pubs, you will learn the material for the writtens. All Sheppard and Dauntless and everyone else do is provide context and organize the information in more accessible ways.
My own experience: I find that studying for the writtens forces me into an independent study path so that I understand WHY particular answers are correct or not. I was never a good student and I don't have great study habits - the writtens have frequently provided me a good road map to follow so I can learn the how and why as well as the what.
I still feel like there is no substitute for a good discussion with a CFI who is really knowledgeable on a subject - I learned more about p-factor and propeller characteristics over beers in a DC bar (ask
@hook_dupin ) than anywhere else.
But it was the studying of the material that gave me the right questions to ask.
Does that make sense?
