If you're studying for your TCCC certification or just trying to stay sharp, finding good practice material is harder than it should be. Most study resources are either locked behind paywalls, buried in 200-page PDFs, or outdated by two guideline cycles.
We built a free TCCC quiz at medeor.app that covers the full MARCH protocol, hemorrhage control, airway management, respiration, circulation, and hypothermia prevention. Every question includes a rationale explaining why the correct answer is correct and why the wrong ones are wrong. That second part matters. Knowing that a tourniquet goes 2-3 inches above the wound is useful. Understanding why you never remove a failed tourniquet in the field is what keeps someone alive.
The questions pull directly from current Committee on TCCC guidelines and Joint Trauma System clinical practice guidelines. We verify every answer against the source material because getting this stuff wrong isn't a bad test score. It's a preventable death.
What the quiz covers
The quiz walks through the major TCCC domains. Hemorrhage control gets the most questions because it's the number one cause of preventable combat death. Over 90% of potentially survivable deaths on the battlefield come from bleeding that could have been stopped.
You'll get questions on tourniquet application, junctional hemorrhage management, wound packing with hemostatic gauze, TXA administration timing, and the criteria for tourniquet conversion. Each one maps to a specific skill you'd need to perform under fire or in a tactical field care environment.
Airway and respiration questions cover NPA insertion, surgical cricothyrotomy indications, chest seal application, needle decompression site selection, and tension pneumothorax recognition. The quiz tests both the "what do I do" and the "when do I do it" because knowing how to perform a needle decompression doesn't help if you can't recognize when one is needed.
Why rationales matter
Most TCCC quizzes give you a score and move on. That's fine for validation but terrible for learning. We include a detailed rationale with every single question. If you get it wrong, you know exactly what you missed and why. If you get it right, the rationale reinforces the underlying principle so it sticks.
For example, one question asks about TXA administration. The correct answer is to give it as soon as possible after wounding. The rationale explains that TXA inhibits fibrinolysis to stabilize clots and that earlier administration provides the greatest survival benefit. The 3-hour restriction has been removed from current guidelines. That's the kind of context that transforms rote memorization into actual clinical understanding.
How to use it
Head to medeor.app and pick any training module. No account needed, no email capture, no paywall. The quiz tracks your progress locally on your device so you can pick up where you left off. It works on your phone, tablet, or laptop, and it works offline once you've loaded it.
If you're a 68W, a corpsman, a PJ, an 18D, or anyone going through CLS certification, this is built for you. By someone who spent 17 years doing the job.
