What the Faa Ap General Practice Test Actually Is
The FAA A&P General practice test covers the material you need to pass the General written exam for your Airframe and Powerplant mechanic certificate. It tests knowledge of mathematics, physics, reading blueprints, using measurement tools, understanding aircraft materials, and basic maintenance procedures. The actual FAA exam has 50 questions and gives you three hours. The practice versions you find online usually have anywhere from 30 to 100 questions depending on the source. I ran through multiple practice tests when I was studying for mine back in 2009. The FAA book is the official source, and most people end up working through either the FAA-H-8083-30 textbook or some third-party question bank. Both work, but they have different problems attached to them. I'll get into that.
Faa Ap General Practice Test Resources
You can download practice tests for free from sites like Aviation Supplies & Academics, FAADirectEd, and various mechanic forums. ASA publishes a dedicated practice test book called the "A&P Mechanic General Test Guide" which is basically just practice questions with explanations. It's around $15 and probably the cleanest single resource you can get. FAADirectEd has a free online option if you don't want to buy anything. The questions on FAADirectEd match the official FAA question bank pretty closely, which matters because the real exam pulls directly from that pool. Here's the thing most people miss when they start studying. The General test isn't hard because the concepts are complex. It's hard because the questions are worded in a way that makes you second-guess yourself. You'll see something like "Which of the following is NOT a characteristic of a good electrical conductor?" and you'll read it fast and circle copper because you were thinking about resistors instead of conductors. I lost three questions on my actual exam to misread answers. That's almost half a passing score right there. The FAA scoring threshold is 70%. You need 35 out of 50 correct. It's not brutal, but the questions come fast and they don't give you much breathing room between topics. One minute you're doing algebra for fuel consumption, the next you're identifying types of welds from a diagram.
How to Actually Use Practice Tests Without Wasting Time
Most people take a practice test, score it, and move on. That's not useful. Here's what works: take a test under real conditions. Set a timer for 72 minutes, no phone, no notes, no looking up answers during the exam. When you finish, go through every single question you got wrong and understand why the right answer is right AND why each wrong answer is wrong. The explanations in the test guides matter more than the questions themselves. I found that taking practice tests in blocks of 25 questions helped more than doing all 100 at once. Your brain gets fatigued after 25 questions and the quality of your answers drops. Breaking it up lets you track where the mistakes actually happen. One specific problem I ran into was with the math questions involving metric conversions. The FAA test occasionally includes questions about metric measurements even though most American mechanics work in inches. I kept getting tripped up because I'd convert 2.5 inches to millimeters wrong and then pick the closest answer. The workaround was simple: I memorized a small conversion table and taped it to my desk while studying. Multiplication table, fractions to decimals, and inch-to-millimeter conversions. It took me about 20 minutes to learn and saved me maybe 8 minutes on the actual exam, but those 8 minutes were the difference between rushing and finishing calmly.
Get the Full Details
Another counter-intuitive thing about the General exam: the math sections are smaller than you'd think. Out of 50 questions, maybe six to eight are pure math. The rest is concept recall and application. Don't spend two weeks drilling algebra. Spend more time on materials, corrosion prevention, and basic physics. Those topics show up consistently across the test and the questions tend to be more nuanced.
Common Pitfalls and Where the Practice Tests Fall Short
Third-party practice tests sometimes have outdated questions or incorrect answer keys. I caught at least two errors in a popular free practice test I downloaded from a random aviation site. One question about heat treatment had the wrong answer marked, and another question referenced an older FAR part number that had since been renumbered. If you're using a free resource, cross-check any answer you're unsure about against the official FAA handbook or the ASA guide. The ASA book answers are vetted against the current question bank, so they're more reliable. The biggest limitation of practice tests in general is that they can't replicate the computer-based testing environment perfectly. The actual FAA computer test sometimes presents questions in a slightly different order or with answer choices shuffled in ways that throw people off. Also, you don't get the same level of time pressure during practice. On the real exam, the clock is visible and it creates a kind of background anxiety that practice tests don't trigger. If you're comfortable with the material, this usually doesn't matter. If you're borderline, it can cost you a few extra wrong answers from second-guessing. If your goal is just to pass, a solid practice test program plus the FAA test guide should take most people about two to three weeks of focused study. People who already work in the industry and touch these concepts daily often pass on the first try after a week of review. People who come at it cold might need three or four weeks. I've seen both.
There's no shortcut around actually learning the content. The questions rotate but the topics stay the same. Focus on the areas you consistently miss, not the ones you already know. That's where the time goes fastest.
