Editorial Policy
Exactly how MedLumen's exam content is created, referenced, checked and corrected — including the parts most platforms don't talk about.
1. How our questions are written
MedLumen questions and explanations are written by hand by our team — doctors who have actually sat and passed these exams — and checked by other humans before they go live. We are not a chatbot generating answers on the fly: nothing is invented the moment you open it. Every question is mapped to its exam's official public blueprint (DHA, PLAB, USMLE, MRCP, SMLE, FMGE and others), and on top of that human authorship we run automated quality gates — structural validation, answer-key balance checks, duplicate detection, and a minimum-explanation standard. Every question is an original clinical vignette; we do not copy, scrape or recycle "remembered" exam questions, which would be both a copyright problem and an exam-integrity violation. AI does not write the medicine here — see section 5 for exactly what it does and doesn't do.
2. References on every new question
New questions are required to cite open-access clinical sources (NICE CKS, WHO guidance, StatPearls, national guideline bodies) in a visible references block, so you can verify the reasoning yourself rather than take our word for it. Currently 55% of the bank carries references, and that number grows with every content batch.
3. The correction loop — every user is a reviewer
Every question carries a ⚑ Report button. Flag an error — clinical, factual, or even a typo — and it lands directly in our review queue. Flags are reviewed and the question is corrected, re-referenced or removed.
4. Physician review
Topics marked "Medically reviewed" have been read and approved by a licensed physician whose name, credentials and registration number appear on the page. 94 topics carry physician review so far, and coverage grows as our reviewer network expands.
You can see our reviewers — real names, credentials and registration numbers — on the Medical Review Board. Are you a licensed doctor preparing with MedLumen? Get in touch — reviewers receive free lifetime access and a public, citable profile credit.
5. What AI does and doesn't do here
- AI does: act as your in-app tutor (explain a concept or answer follow-up questions when a hand-written explanation isn't enough), map your weak areas from your performance, and drive flashcards and Spaced Review — resurfacing the questions you're about to forget so human-written material actually sticks. Behind the scenes it also helps our team build and organise faster.
- AI doesn't: write or approve the questions and explanations that ship to you — people do that. It also doesn't invent exam statistics, diagnose patients, or replace the official curricula. Always check current official sources (GMC, DHA, USMLE/ECFMG, SCFHS, NBE) for registration, dates and fees.
6. Updates & freshness
Study guides and questions are regenerated and re-checked in batches; pages show their last-updated date. When guidelines change (resuscitation protocols, antibiotic policies, screening intervals), the correction loop and content refreshes catch up — and the ⚑ button means you can force the issue the moment you spot a discrepancy.
