If you are preparing for MRCPsych Paper B and using PassMRCPsych, this audit is about transfer: which of its question styles rehearse the real paper and which do not. PassMRCPsych is an affordable, high-volume bank that covers Paper B's clinical topics well and bundles a dedicated statistics course. Its principal limitation is that Paper B's substantial critical-appraisal and statistics component rewards worked reasoning over a paper or dataset, and a recall-weighted MCQ bank can teach the definitions without rehearsing the reasoning the examiners actually score.

Bundling a statistics course is the right instinct for Paper B, and the price is keen. Whether the critical-appraisal items rehearse reasoning rather than recognition is the question that determines how much of your practice actually transfers.
The exam you are actually preparing for
MRCPsych Paper B is a written paper of MCQs and extended matching items, approximately two-thirds MCQ and one-third EMI, of the order of 150 questions in three hours at Pearson VUE — confirm the current count and duration on rcpsych.ac.uk. It has two broad strands: a substantial critical-review component (research methods, statistics, critical appraisal, evidence interpretation) and clinical topics across the psychiatric subspecialties. The critical-review strand is what distinguishes Paper B from Paper A, and it is the part most vulnerable to being "learned" as facts rather than practised as reasoning. The College's sample paper shows the intended pitch; use it as your calibration standard.
Reading the headline count by blueprint domain
A "5,000+" total says nothing about how the items distribute across Paper B's blueprint, and the clinical-versus-critical-review balance is exactly where a bank can quietly under-serve you. Audit by domain rather than by completion percentage, using the blueprint-coverage matrix method.
| Paper B domain | What it demands | Bank behaviour to check |
|---|---|---|
| Research methods & study design | Recognising designs, bias, confounding | Often present but recognition-pitched |
| Statistics | Calculation and interpretation (e.g. NNT, likelihood ratios) | Verify worked calculation, not just definitions |
| Critical appraisal | Judging a paper's validity and applicability | The hardest to rehearse in MCQ form |
| Evidence interpretation & clinical policy | Applying evidence to practice | Check for guideline-anchored items |
| General adult & subspecialty clinical | Diagnosis and management across services | Usually the bank's strongest area |
If the bank's strength is clinical recall and its critical-review items are thin or definition-led, you have located the gap most likely to cost marks.
Question style: what transfers and what does not
Score a stratified sample on recall versus application, stem length, option plausibility, and whether the item requires data interpretation or a management sequence. The clinical items generally transfer well: Paper B's clinical questions are recall-and-reasoning hybrids that a good bank rehearses faithfully. The critical-appraisal items are where transfer breaks down. A well-written appraisal item makes you read a described study and judge validity; a weak one asks you to name a bias from a definition. The first transfers to the exam; the second trains recognition. Statistics items transfer only if the explanations show the working — an answer that states "the NNT is 25" without the arithmetic teaches the number, not the method.
Jurisdiction and recency
Paper B is anchored in UK practice and current evidence, so recency matters more here than for the basic sciences. When you spot-check a sample, cross-reference clinical-policy items against current national guidance and any drug specifics against the SmPC/eMC, and record your review date. Evidence-interpretation items age faster than pure statistics, because the underlying trials and guidelines move; a bundled statistics course dates more slowly. Flag any item whose "correct" answer depends on superseded guidance.
The format gap: what an MCQ bank cannot fully rehearse
State it plainly: a standard question bank can prepare you for Paper B's clinical strand and for the mechanics of statistics, but it cannot fully rehearse critical appraisal, evidence interpretation and clinical-policy judgement on its own. These reward the ability to reason across a described study or scenario, weigh validity and applicability, and reach a defensible conclusion — a process that lives uneasily inside a five-option stem. The bank is necessary for coverage and for statistical fluency; it is not sufficient for the appraisal reasoning, which also needs practice reading real abstracts and applying a structured critique.
Duplication and contamination: when completion becomes recognition
Paper B banks are especially prone to a specific trap: the same statistical scenario, re-skinned, so that by the third pass you recognise "this is the likelihood-ratio one" without doing the reasoning. That is recognition masquerading as competence, and it is dangerous precisely because Paper B's marks hinge on method. Tag items you answered from memory of the stem and retire them, and hold back a reserve of unseen critical-appraisal and statistics items so you can measure genuine reasoning late in your preparation — the logic of why a Q-bank percentage is not your exam score.
Best-fit matrix: where PassMRCPsych earns its place
| Revision job | PassMRCPsych fit for Paper B |
|---|---|
| Clinical-topic breadth | Strong — a sensible primary bank |
| Statistics mechanics | Reasonable — the bundled course helps; verify worked examples |
| Critical-appraisal reasoning | Weak on its own — supplement with real-paper practice |
| Second bank for triangulation | Reasonable — manage overlap |
| Final unseen simulation | Weak — used items no longer measure readiness |
PassMRCPsych is strongest on the clinical strand and on statistical mechanics, and weakest as a stand-alone rehearsal of appraisal reasoning and as a final-week readiness gauge.
A seven-day worked example for a busy core trainee
Assume a trainee eight weeks out, on full shifts. Give PassMRCPsych one job — clinical breadth plus statistics mechanics — and give iatroX another: unseen transfer measurement, especially on critical appraisal. No proprietary-algorithm claims are needed; this is spaced retrieval and honest sampling.
- Monday: 40 clinical-topic items; log misses by reasoning error, not just topic.
- Tuesday: The statistics course plus 20 worked calculation items; redo each calculation by hand.
- Wednesday: A critical-appraisal set; for each, write one sentence on the study's main validity threat.
- Thursday: Re-test Monday–Wednesday misses after a gap.
- Friday: Read one real abstract and critique it in five lines — validity, applicability, conclusion.
- Saturday: A fresh, timed MRCPsych Paper B block in iatroX on unseen items — your readiness reading, kept separate from the bank.
- Sunday: Review only the iatroX misses, prioritising any appraisal errors; rest.
Keeping practice and measurement apart is the discipline of the two-Q-bank rule. Calibrating your own appraisal judgement before you trust a score is the same principle behind calibrating automated feedback.
Decision checklist: continue, supplement, switch or stop
- Continue if your unseen clinical scores are rising and your appraisal reasoning is improving on fresh items.
- Supplement — almost always — with real-abstract critique for the critical-review strand, because MCQs alone under-rehearse it.
- Switch your primary bank only on a measured fidelity gap: definition-led appraisal items, or statistics explanations that hide the working.
- Stop adding new items in the final week; move to timed unseen mocks that mix clinical and critical-review questions in exam proportions.
Three mistakes this audit is designed to stop
First, treating a bias definition as appraisal practice. Naming "selection bias" from a textbook definition is recognition; judging whether a described trial is valid and applicable is the task Paper B actually scores, so do the latter on real abstracts, not only in multiple-choice form. Second, memorising statistics answers without the working. An explanation that states the number needed to treat but hides the arithmetic teaches a figure, not a method — and it is the method the examiners test, so redo every calculation by hand until it is automatic. Third, confusing a rising bank percentage with readiness. On a bank you have worked several times, the number climbs because the stems have become familiar, not because your reasoning has improved; measure on unseen items and let that, not the completion figure, tell you whether you are ready.
Bottom line
For MRCPsych Paper B, PassMRCPsych's clinical questions and statistics mechanics transfer well, and at its price it is a reasonable primary bank. What transfers less well is critical-appraisal reasoning: an MCQ that names a bias from a definition is not the same task as judging a described study, and Paper B scores the latter. Use PassMRCPsych for clinical breadth and statistical fluency, add structured real-paper critique, and measure readiness on unseen items you have not already learned.
Frequently asked questions
Is PassMRCPsych enough for MRCPsych Paper B on its own? It can carry the clinical strand and the mechanics of statistics, but on its own it under-rehearses critical-appraisal reasoning, which is a substantial part of Paper B. "Enough on its own" also ignores measurement: once you have worked the bank, your score reflects familiarity. Pair it with real-abstract critique and an unseen reserve for readiness.
Which MRCPsych Paper B component does PassMRCPsych not reproduce well? Critical appraisal is the weakest transfer, on a 20 July 2026 review. Judging the validity and applicability of a described study is a reasoning task that sits awkwardly in a five-option MCQ, so a bank tends to convert it into recognition of definitions. Rehearse appraisal on real papers alongside the bank, not instead of it.
How many PassMRCPsych questions should I complete per day for MRCPsych Paper B? No official target exists; treat any figure as personal. A working trainee can sustain around 40 to 60 fully reviewed items on weekdays, but for Paper B the review is doubly important — redo every statistics calculation by hand and articulate every appraisal judgement, because that is where the marks are won.
When should I stop using PassMRCPsych and move to mixed mocks? Move in the final ten to fourteen days, once your first pass is complete and you are recognising stems. Timed mixed mocks that blend clinical and critical-review items in exam proportions rehearse pacing and transfer; further first-pass drilling mostly rehearses memory of specific questions.
How should I combine PassMRCPsych with iatroX without duplicating practice? Assign non-overlapping jobs. Use PassMRCPsych for clinical breadth and statistics mechanics, and reserve iatroX for fresh, timed, unseen blocks — especially on critical-review items — that measure transfer. Never run the same content through both; the second source only adds value while it stays unseen, which is the core of the two-Q-bank rule.
