What King School's Part 107 Practice Test Actually Does
The King School Part 107 Practice Test is one of the more widely used free prep tools for people studying for the FAA remote pilot knowledge exam. You take a series of multiple-choice questions that roughly mirror the format and difficulty of the real test, and it gives you a score at the end along with explanations for the answers you missed. It is not the official FAA test, and it will not predict your exact score, but it is useful for identifying weak spots before you go in. I started with a free King School Part 107 Practice Test after reading the AC 107-1A and the FAA test guide, then repeated it three more times before booking my actual slot. The process is straightforward: go to the King Schools website, find the Part 107 section, and select the practice test. It generates a set of roughly 50 questions in about the same structure as the real exam. You answer each one, move on, and when you finish it grades everything. The ones you get wrong show the correct answer with a short explanation. The real value is not the score itself. The FAA exam has about 60 questions and you need 70% to pass, which is roughly 42 correct. Most people who study enough will clear that bar on the actual exam even if their practice scores hover around 60%. What matters is where you are consistently missing questions. If you keep getting chart-reading questions wrong, you need to spend time on Sectional Charts and the TOC. If weather questions keep tripping you up, you need to review Part 107.29 and Part 107.37 more closely.
One thing I learned the hard way is that the King practice tests lean heavily toward certain topics and sometimes skim others. I took four practice tests and never saw a single question about operation over human beings, even though that appeared on my actual exam. That is a limitation you have to work around. I ended up supplementing with the FAA test questions PDF and the study guides from another source just to cover the gaps.
What the King School Practice Tests Get Right
The explanations for wrong answers are concise and usually point you toward the right reference. A lot of the questions use realistic scenarios instead of dry recall prompts, which helps because the real FAA exam does the same thing. The interface is clean. There are no pop-up ads during the test, no weird timers that rush you, and no requirement to create an account to start. You just open it and go. I also noticed that the difficulty curve is fairly consistent across different practice test attempts. That means retaking the same test or switching to a different form gives you a reliable comparison of whether you are improving. When my score climbed from 58% to 76% over three attempts, I had a reasonable signal that I was ready. I scheduled the actual exam the next week and passed on the first try with a score of 81%.

Pitfalls I ran into
The biggest issue I found is that some of the answer choices are almost identical, and the questions can be worded in a way that feels ambiguous until you read the explanation. For example, a question about maximum altitude over a stationary observer might list two similar altitude answers depending on whether you factor in terrain elevation or obstacle clearance. The real exam sometimes does this too, so practicing with that ambiguity helps, but it can also make you second-guess yourself during the actual test. Another problem is timing. The King practice test does not impose the same time pressure as the real exam. You can take as long as you want per question. On test day, I finished in about 40 minutes with roughly 20 minutes to spare, but that was because the questions were mostly familiar. If you are going in cold, the time limit becomes relevant and you need to practice under it. I did a quick workaround by setting a timer on my phone for 60 minutes during my last couple of practice runs and forcing myself to move on when it went off.
Where King School Falls Short
The King School Part 107 Practice Test covers a broad range of topics, but it is not exhaustive. Certain FAA test questions like those involving airspace classification changes on an update, or specific night operations rules beyond the basics, do not always appear. You should treat it as a starting point rather than a complete study plan. If you rely on it exclusively, you will miss material. The explanations are also pretty brief. When you miss a question about minimum control speed or weight and balance calculations, the explanation might not walk you through the math step by step. You have to go back to your study guide or watch a video to fully understand why the answer is what it is. That is fine if you are already deep into the material, but if you are just starting, it can leave you stuck on a concept for longer than you need to be. I also encountered a few questions that seemed outdated or poorly worded. One question referenced a regulation number that had been reorganized, which made it confusing even after reading the explanation. The FAA periodically updates their test guide, and third-party practice tests can lag behind that. It is worth cross-referencing with the latest FAA test question PDF released by the agency, which is free and updated annually.
Practical approach that worked for me
I took the King School Part 107 Practice Test early to get a baseline, then spent about two weeks studying with a mix of the FAA test guide, a YouTube series on charts and weather, and flashcards for regulations. After that, I took the practice test again and repeated it until my scores stabilized above 75%. I also did a full timed run the night before the exam to simulate the real conditions. I went in calm, finished in 40 minutes, and passed comfortably. If you want a cheaper or alternative option, the FAA's own free online testing tool is just as accurate because it pulls from the official question bank. The King version is useful mainly for its scenario-style questions and the ease of retaking multiple forms without creating an account. I would use both if possible, but the King practice test alone is not enough to guarantee a pass. The main takeaway is to use it to find gaps, not to confirm readiness. Score is secondary to understanding why you got something wrong. The exam tests application, not rote memorization, so practice questions that force you to reason through a scenario are more valuable than ones that just ask for a number you happened to memorize. Keep working until the weak topics stop showing up, then schedule the exam.
