Most candidates preparing for a clinical examination can accumulate a genuinely impressive amount of knowledge and still find themselves struggling on the day, not because the knowledge was wrong, but because organising it into a safe, coherent performance under time pressure is a different skill entirely, one that reading, question banks and lectures rarely rehearse directly. That gap, between knowing and demonstrating, is what iatroX Simulations is built to close.
What iatroX Simulations adds
Eighteen examination-specific tracks, each built around what that particular exam actually assesses rather than a single generic template stretched across every one of them. Clinician-reviewed cases throughout, a proof point covered in full in the dedicated methodology article this launch is built alongside. Responsive voice and text interaction, so a candidate can practise however suits a given session rather than being locked into one input mode. Isolated practice for focused, single-station work and full mock circuits for the sequential, stamina-testing experience a real examination day actually demands. Examination-specific feedback, scored against the domains that particular assessment actually marks. Transcript-linked evidence, so every piece of feedback traces back to what the candidate genuinely said or did, not an unexplained number. Tutor-led remediation, turning a weak performance into a specific, worked correction rather than leaving the candidate to guess what to fix. Prescribed next cases and readiness tracking, showing progression across a preparation period rather than one isolated score. And availability on the web and through the native iatroX app, so practice fits around a working week rather than requiring a fixed desktop session every time.
The complete iatroX learning loop
Learn, retrieve, perform, inspect, remediate, repeat. This loop is the genuine product story, more than any single feature within it. A candidate identifies a knowledge gap through the Q-bank, works through it with the Socratic Tutor, then takes that knowledge into a simulated performance where it has to hold up under realistic pressure, inspects exactly what happened through a transcript-linked review, returns to the Tutor to repair whatever the performance actually revealed, and moves to the next case with that specific correction behind them. Each stage feeds the next, which is what makes this a system rather than a collection of separate tools bolted together.
What one simulation contains
A candidate brief, setting the scenario and task clearly before the interaction begins. The interaction itself, responsive rather than scripted, evolving as the candidate's own questions, decisions and communication actually unfold rather than following a fixed predetermined path. Evolving information, where relevant to the case type, mirroring how real clinical situations change rather than presenting a static picture throughout. A defined completion point. A full transcript of the encounter. Feedback linked directly to that transcript, showing precisely which moment produced which observation. Tutor access for interrogating any weakness the feedback surfaced. And a subsequent recommendation, the specific next case suggested based on what this attempt actually revealed.
How the examinations differ
iatroX does not force every examination into a generic spoken-patient template, because most exams do not actually test the same thing. USMLE Step 3 CCS, for instance, is built around management and order-entry mechanics, sequencing decisions and case navigation rather than a conversational patient encounter, and the simulation track for that exam reflects that structure directly rather than dressing it up as an artificial conversation it was never designed to be. Other tracks genuinely do involve patients, and others involve colleagues, examiners, structured case discussion or viva-style interaction, because that is what those specific examinations actually assess. Matching the interaction model to the real exam, rather than applying one interaction model everywhere, is a deliberate design choice running through every one of the eighteen tracks.
Clinician review and continuous improvement
Every case in this catalogue is clinician-reviewed, a standard applied consistently across all eighteen tracks rather than to a selected subset, covered in full detail, including exactly what that review process involves, in the dedicated methodology article. The product is also actively and continuously improved, through user reporting, clinician re-review, behavioural testing and monitored production performance, the specific process this launch's companion article on continuous improvement sets out directly.
What simulation does not replace
Stated plainly, because an honest launch says this clearly rather than leaving it for a sceptical reader to discover unprompted. Bedside exposure to real patients. Physical examination technique, where an exam genuinely requires eliciting and interpreting real signs. Procedural and operative practice, wherever hands-on skill is being assessed. Genuine human feedback from trainers, examiners and peers, whose judgement and experience remain irreplaceable for the qualities simulation cannot fully capture. iatroX Simulations exists to rehearse the performance around and alongside these irreplaceable elements, not to substitute for them.
Access
One complete simulation is available to try free, genuinely complete, the full interaction, results, transcript and Tutor support where applicable, rather than a shortened demonstration. Beyond that, unlimited simulation access across all eighteen tracks sits inside the same all-access subscription as the rest of iatroX, question banks, Tutor, planning and CPD, monthly or annually.
Frequently asked questions
How many cases are available at launch?
1,114 clinician-reviewed cases across the eighteen examination tracks at launch, a figure that will continue to grow as coverage expands; the current count is checked and stated at the point of publication.
Does one subscription cover more than one examination?
Yes: the same all-access subscription that covers iatroX's question banks and Tutor also covers every simulation track, meaning a candidate preparing across more than one examination, PLAB and a Royal College exam, for instance, is not paying separately for each.
Is the free simulation a shortened demo?
No: it is one genuinely complete simulation, the full interaction, transcript, feedback and Tutor access where applicable, specifically so a candidate can judge the entire learning loop before subscribing rather than a truncated preview.
