No one has the same questions as the FAA test. Not Sheppard, not Dauntless, not Gleim. They know what subject matter will be covered and have collected questions from old tests and feed back they get from people who take the new tests but no one has all the current FAA test questions.
I've even heard with the computer based testing the FAA can move the answers around. So you can't just say all the questions about magnetic variation are "B". On your test "B" may be the correct answer. For a person taking the same test with the same question sitting next to your the answers can be shuffled so the correct answer is "A" or "C".
