Most people fail the Part 107 exam not because they don't study, but because they study the wrong way. Passive reading feels productive, but it doesn't train recall under pressure. The FAA knowledge test is specific, timed, and weighted by topic. You need to practice under exam conditions — the same constraints you'll face at a PSI testing center — so your brain learns to retrieve facts when it matters.
What the actual FAA exam looks like
The official exam is the Unmanned Aircraft General – Small (UAG). You'll answer 60 questions drawn from six topic areas defined in the FAA Airman Certification Standards (ACS). You have 2 hours to finish. The passing score is 70%, which means you need at least 42 correct out of 60.
Questions are not evenly distributed. Topic weighting on the exam is approximately: Airspace (20%), Weather (18%), Regulations (15%), Airport operations (17%), Loading and performance (17%), and Physiology and ADM (13%). That means airspace and weather alone account for more than a third of your score — if you only skim those chapters, you're taking a real risk.
You'll sit for the test at a PSI testing center. The exam fee is typically around $175, though some locations charge less. You need an FAA Tracking Number (FTN) before you book — but you don't need to guess what the room will feel like. You can rehearse the pacing and pressure with a practice exam that uses the same structure: 60 questions, one timer, one shot at demonstrating you know the ACS cold.
Why most practice exams fall short
Many apps give you a long list of questions and call it "prep." That helps a little, but it doesn't match how the FAA builds your real test. If every practice session pulls questions in random proportions, you might walk in thinking you're strong on regulations when you're actually weak on airspace — where the exam hits hardest.
- Random topic mix hides your gaps until it's too late.
- No breakdown after the attempt means you don't know whether you missed METAR questions, chart symbols, or Part 107 limits.
- No weak-area map makes your study plan a guess instead of a plan.
The fix is simple in theory: practice with weighting that mirrors the real exam, then review results by topic so you know exactly what to study next.
How VLOSready's practice exam works
VLOSready is built around the same structure the FAA uses. The bank includes 529 questions written to reflect ACS-style wording and difficulty. Each full exam is a 60-question draw weighted to match the real UAG distribution — so your practice sessions feel like the real thing, not a trivia lottery.
- 2-hour timer to build pacing and reduce surprise on test day.
- Detailed results by topic so you see where you lost points — airspace, weather, regulations, and the rest.
- Unlimited retakes as you improve; each attempt is a new weighted draw from the bank.
- Start with a free account and build from there.
Topics you'll be tested on
You don't need to memorize the ACS cover to cover in one sitting — you need a working command of the ideas the FAA tests most often. Airspace classes, weather products, Part 107 operating rules, chart literacy, loading and performance concepts, and decision-making frameworks all show up in proportions that match the weights above. When you practice with those weights, you naturally spend mental energy where the exam spends its questions.
Think of each topic as a bucket: fill the big buckets (airspace, weather, airports) first, then tighten the smaller ones (physiology, ADM) so nothing surprises you on exam day.
Take the timed practice exam and see your strengths by topic.
The best time to take your first practice exam is before you feel ready. Your score isn't a verdict — it's a map. It tells you exactly where to focus your next week of study so you walk into PSI confident, not guessing.
