Each choice leads somewhere different, and every path ends with a debrief that explains why it was right or wrong and cites the guideline or trial behind it.</p> <p><strong>How it's delivered.</strong> Critical is a single static HTML file hosted on GitHub Pages, so there's no backend, no login and no data collected beyond anonymous page-visit counts.</p> <p><strong>Limits.</strong> It's a practice tool, not medical advice, and no physician has formally reviewed the full bank yet. If you find an error, you can report it through the project's GitHub issues page.</p> <p>Try it: <a href="https://xairu23.github.io/Critical/" rel="noopener noreferrer">https://xairu23.github.io/Critical/</a></p> <p>What would make it more useful to people studying for Step 2?</p> webdev education showdev opensource
