The FAA does not publish test questions, in fact they prohibit copying and publication of test questions and answers. Anyone taking a course where all they do is study and memorize test questions and corresponding answers is not studying for an FAA written test. What they are doing is studying an estimation of the FAA test, developed independent of the FAA and the actual test. In essence, someone following that path has no assurance they learned anything at all relevant to the actual FAA exam. That condition is worsened if the student has chosen a recently established course developed by people with little or no previous history in developing or providing an aeronautical knowledge curriculum. Unless the “school” has been certified under part 61, 135, or 141 rules there are no standards, or penalties (other than for the student) for failure.
There are online courses available from reputable, long standing companies serving the pilot community that have 20 years or more of successful history in educating students. They aren’t the cheapest but the history of success with their students is indicative of the course quality. For the cost conscious there is no reason to buy a course at all. Everything needed to study for and pass the test is provided for free by the FAA. Downloading the books, reading them, then reading them several times more will provide the knowledge necessary to pass the test, the first time. If the student encounters things they don’t understand they can ask questions at forums such as this one.
As the OP has already failed the test twice, spent $300.00 plus the cost of his course and gotten nowhere in the process, perhaps it’s time to take a step back to review what has been done wrong. The only lesson learned thus far is that what has been done does not work. Was it the course chosen, lack of accurate and applicable material, inability to digest and comprehend the material, poor study habits, or any combination of the those? Blaming the FAA for requiring and providing a test and testing methods that every certificated pilot has successfully passed is only trying to avoid personal responsibility. “It can’t be my fault as nothing is ever my fault.” That’s not the way life, or aviation, works.
Something else to consider; passing the test does not mean you now know everything. Passing the test means you will be legally qualified to participate in an activity where the is much, much more to learn. Something you will be expected and required to do to survive. The certificate is but a license to learn.
The above was given the OP from the perspective of an FAA ground instructor. Only the OP can decide how he wants to make use of it.
