Methodology
How PassCurve questions are written and checked
Every question a candidate sees is built the same way and checked the same way, exam after exam. This page sets out that process in full: what a question is checked against, what happens to the ones that fail the check, and where AI sits in the pipeline. Read it, and you will know exactly what "evidence based" means when PassCurve uses the phrase.

Built against the blueprint
Where an exam publishes a percentage blueprint, the SMLE and the SNLE, PassCurve writes and balances sessions to those exact weights. Where a regulator does not publish one, which is most of the exams PassCurve covers, the four clinical domains those exams describe (internal medicine, surgery, paediatrics, and obstetrics and gynaecology) are still covered evenly rather than drifting toward whichever is easiest to write questions for. The exam comparison sets out exactly which exams publish a blueprint and which do not.
Checked against a named guideline
A question is not published on the strength of what a model happens to recall. Its correct answer is checked against a specific, named clinical guideline or reference: a professional body's published guidance, a major reference text, or a regulator's own standard. "Evidence based" on PassCurve means that check happened and the source is named, not a general claim about how the question was drafted.
The source travels with the question
Every published question carries its source and the date that source was last read, for the life of the question. You see this on the answer screen itself, not in a changelog you have to go looking for: which guideline, and when it was last checked against it. A question that cannot be traced to a named source is not published.
When guidance changes, the question comes back
Clinical guidance moves. A drug falls out of first line use, a threshold shifts, a professional body issues an update. PassCurve treats "checked once" as exactly that, not "checked forever": when the guidance behind a question changes, the question is queued for another read against the current source, and its explanation and citation are updated to match. The checked date you see is the last time this happened, not the date the question was first written.
What doesn't make it in
Not every drafted question survives the check. A question whose answer cannot be traced to a named source, or whose source turns out to be outdated, wrong, or contested, is not published. There is no partial credit for a well written stem carrying a shaky answer: a question either clears the check, or it does not go live.
Aimed at your weakest subject, and what you miss comes back
Writing and checking a question is half the method; the other half is what happens once it is in front of you. A mixed session is built to the exam's weights first, then tilted toward whichever subject is currently costing you marks, using a per subject rating that moves as you answer. Anything you get wrong joins your review deck, scheduled on a spacing curve so you meet it again shortly before you would have forgotten it. Reviews stay free forever, on every plan.
Written with AI assistance, and we say so
PassCurve's questions and explanations are written and fact-checked with AI assistance. They are not individually signed off by a physician, and PassCurve makes no claim of physician review, expert review, medical accreditation, or endorsement by any exam authority. That trade is made openly rather than implied away: consistency and a named, dated source on every single question, at the scale eight exams' worth of content requires, in place of a doctor-by-doctor sign-off this kind of project could not honestly promise alongside it.
Despite the checks, content is not guaranteed to be error free. The in-product report button is the fastest way to flag a correction, and a reported question is reviewed directly against its source.
What this is not
PassCurve is a revision aid. Its content is for exam preparation only, and it must never be used for clinical decisions or patient care. PassCurve does not guarantee exam results.
PassCurve is an independent revision tool. It is not affiliated with, endorsed by, or accredited by the Saudi Commission for Health Specialties, the Dubai Health Authority, the Department of Health Abu Dhabi, Qatar's Department of Healthcare Professions (DHP/QCHP), the Ministry of Health and Prevention (MOHAP), the National Health Regulatory Authority (NHRA), Kuwait's Ministry of Health, Prometric, Pearson VUE, or any other exam authority.
