This audit is for anaesthetics trainees using Pastest to prepare for the Primary FRCA MCQ while working clinically. Pastest is a strong, well-established bank for this exam, and the short version is that its analytics optimise coverage and re-exposure within its own question set, plus a within-bank readiness indicator — not readiness against the Royal College of Anaesthetists (RCoA) blueprint, and certainly not the oral and OSCE components that no written bank can replace. Read its dashboard as a map of how well you know Pastest's questions and you will read it correctly; read it as a pass predictor and it will mislead you.
That is not a criticism of the product so much as a description of what any Q-bank engine can and cannot do. A selection algorithm optimises whatever it can measure, which is behaviour inside its own bank: which items you have seen, missed, or flagged, and how your percentage is trending. It cannot see the RCoA standard, and it cannot see the structured oral and clinical stations that sit beyond the MCQ gateway. Keeping that clearly in mind is what turns Pastest from a comfortable number-generator into a genuinely useful tool.

The honest nuance behind the title of this article: "adaptive" is doing a lot of work in the market's language. What we could confirm is analytics, an AI tutor, and configurable practice filters, not a published adaptive-difficulty engine. Whatever the exact selection mechanism, the point stands — it optimises within Pastest's bank, and its "readiness" claim is a within-bank indicator, not an RCoA prediction. Because Tutor mode is an AI feature, it is also worth applying the same scrutiny you would to any automated tutor; the iatroX pillar on auditing an AI medical-exam tutor sets out how to check its grounding before you trust it.
The Primary FRCA exam anchor
The current Primary FRCA MCQ is 90 single-best-answer questions in three hours, delivered online with remote invigilation. It is broadly balanced across three subject areas: 30 questions in pharmacology; 30 in physiology, including biochemistry and anatomy; and 30 in physics, clinical measurement, statistics and data interpretation. Multiple true-false questions were removed in September 2023, so the paper is now SBA-only. Critically, the MCQ is a gateway: candidates must pass it before they can apply for the Primary FRCA OSCE and the structured oral examination (SOE). No question bank prepares you for those spoken and clinical stations, a point we return to below.
One further caveat belongs in every current audit. The RCoA has announced new FRCA exam formats planned from July 2027, subject to GMC approval, replacing the OSCE and SOE for candidates without valid partial passes. Under the announced plans the Primary MCQ becomes a "Primary FRCA AKT" of two papers, and a new "Primary FRCA CASE" replaces the oral and OSCE stations. Confirm the timing and detail directly with the RCoA, because a bank optimised for the current format is not automatically optimised for the next one, and your revision timeline may straddle the change.
Every Pastest metric, defined
First-attempt accuracy is your percentage the first time you meet an item, and it is the least contaminated estimate of real knowledge Pastest gives you. Trust it above the headline average.
Repeat accuracy is your percentage on previously seen items. It rises through recognition memory of specific stems and flatters your overall figure; treat improvements here with suspicion.
Percentile or peer comparison places you against other Pastest users. Those users are self-selected and revising on the same bank, so it is a within-bank ranking, not your standing among all Primary FRCA candidates.
Predicted score or "readiness" indicator is marketed to signal exam readiness. No bank can see the RCoA standard, so read any such figure as a within-bank progress indicator, not a pass probability, and never let it substitute for unseen, timed performance.
Coverage is the share of the bank attempted. This is completion, not blueprint coverage; finishing every item does not guarantee even sampling of physics, clinical measurement and statistics, which trainees routinely under-practise.
Difficulty is an item's historical hardness across users, useful for pacing but unrelated to the exam's actual standard.
Time per item is the metric that transfers most directly to the real three-hour paper. If you are slow on calculation-heavy physics and statistics items now, plan for that, because those are the items most likely to eat your clock.
Why the feed biases the numbers
Whether Pastest surfaces items through configurable filters, spaced re-exposure or Tutor-guided review, the statistical effect is similar: you disproportionately re-see material you have already engaged with. That inflates repeat accuracy and the overall average while leaving your unseen, first-attempt ability much flatter. The within-bank "readiness" indicator moves with volume and repetition, so a diligent trainee can watch the number climb chiefly because they are re-answering familiar stems. This is the exact dynamic the iatroX article "Your Q-Bank Percentage Is Not Your Exam Score" describes, and it is why an audit has to look past the headline figure to the first-attempt trend on unseen items.
Blueprint audit: map attempts to the RCoA split
The exam is evenly weighted across three subject areas, so the first thing to check is whether your attempts are too. Build the matrix below from your attempt log and mark each row for volume and first-attempt accuracy.
| RCoA subject area (≈30 questions each) | Common trainee pattern | Audit action |
|---|---|---|
| Pharmacology | Usually well practised; high volume | Confirm breadth across drug classes, not just favourites |
| Physiology (incl. biochemistry and anatomy) | Broad; anatomy and biochemistry often thinner | Force anatomy and biochemistry sub-topics to the surface |
| Physics, clinical measurement, statistics, data interpretation | Frequently under-practised and disliked | Set a hard floor; this is where marks are quietly lost |
The recurring finding across trainees is that pharmacology and mainstream physiology feel comfortable and get over-sampled, while physics, clinical measurement and statistics get avoided precisely because they are uncomfortable. An even blueprint demands even practice, so the audit's job is to make the home-screen average stop hiding that imbalance. The completion-is-not-coverage pillar walks through building this matrix for any exam.
The readiness test: five conditions
A Pastest number becomes a readiness signal only when the items are unseen, the block is timed at the real pace of roughly two minutes per item, the block is mixed across all three subject areas rather than filtered to your strengths, you use no assistance including Tutor mode, and the sample is large enough to be stable across several sittings. Default study modes rarely satisfy all five at once, so if you want a readiness read you must construct these conditions deliberately, or measure on a separate unseen bank kept for that purpose.
Override rules: what to force into the feed
Set floors that force the uncomfortable, high-yield material to appear regardless of what the feed would otherwise serve. Force physics, clinical measurement and statistics every week, because these are the most avoided and the most quietly decisive. Force data-interpretation and calculation items, including the applied maths inside pharmacokinetics. Force anatomy and biochemistry within physiology, which a physiology-heavy learner can skate over. And periodically force a fully mixed, timed block with Tutor mode off, so you experience the real cognitive load of the paper. If the bank cannot serve a sub-area at volume, that is your cue to supplement, not to skip.
Worked dashboard example
Imagine Pastest shows an overall 79%, repeat accuracy 88%, first-attempt 66%, pharmacology 83%, physiology 77%, and physics/measurement/statistics 61% on lower volume. Do not read 79% as a pass probability. Read the 22-point gap between repeat and first-attempt as recognition-memory inflation, and read the low-volume 61% as the real risk. Next week's quotas follow: 40 unseen mixed items, timed; 30 physics, clinical-measurement and statistics items; 15 data-interpretation items; and one fully mixed, Tutor-off block at exam pace. The point of the exercise is to convert a comfortable average into a corrective plan, without inventing a pass prediction the data cannot support.
A seven-day pattern for busy trainees
Revising around clinical shifts means short, high-value sessions. Use Pastest for one job — knowledge and format practice across its bank — and use iatroX for unseen transfer practice and measurement. No claims are made about any platform's internal algorithm.
| Day | Pastest (job: knowledge and format practice) | iatroX (job: unseen transfer and measurement) |
|---|---|---|
| 1 | 30 first-attempt SBAs, mixed subjects | 15-item unseen block, timed |
| 2 | 30 SBAs, physics and measurement focus | 10 statistics and data-interpretation items |
| 3 | Review flagged items; read the linked textbook | 15 mixed items, timed |
| 4 | 30 SBAs, physiology including anatomy | 10 pharmacology-maths items |
| 5 | Tutor-mode review of weak concepts | 15 unseen items, Tutor off |
| 6 | Light; consolidate notes | 30-item mixed block at full pace |
| 7 | Rest or read | Re-audit: first-attempt trend, coverage, pacing |
This mirrors the two-Q-bank rule: one bank teaches and one measures on unseen material, so your readiness signal never gets spent on pre-read questions.
Three mistakes this audit is designed to stop
First, mistaking a within-bank "readiness" indicator for a pass prediction; it optimises Pastest's own metrics, not the RCoA standard. Second, treating the MCQ pass as the finish line; it is a gateway, and no bank prepares you for the structured oral and OSCE stations that follow — plan separate practice for those, ideally with peers and trainers. Third, letting comfort dictate coverage, so pharmacology gets over-drilled while physics, clinical measurement and statistics quietly bleed marks. All three are avoidable once you read first-attempt performance on unseen, mixed blocks as the real signal.
Decision checklist
Continue with Pastest if you value its breadth and you read its numbers as within-bank progress. Supplement with unseen, timed measurement and with dedicated oral and OSCE preparation the bank does not provide. Switch or add a second bank if your matrix shows persistent under-coverage the feed will not correct, following the two-Q-bank rule to avoid duplication. Stop grinding written questions when your unseen, mixed, first-attempt performance is stable across all three subject areas — then shift energy to the spoken and clinical components.
Bottom line
Pastest is a strong, well-populated Primary FRCA bank and a reasonable backbone for the MCQ, worth including in the revision stack. Its analytics, though, optimise coverage and re-exposure within its own questions and offer a within-bank readiness indicator, not a pass prediction and not readiness for the oral and OSCE stations beyond the gateway. Use it for breadth and format fluency, measure readiness on unseen timed blocks, force the physics-measurement-statistics material the feed lets you avoid, and keep an eye on the announced 2027 changes so your plan matches the exam you will actually sit.
FAQ
Is Pastest enough for the Primary FRCA on its own? For the written MCQ, Pastest's large bank can carry much of your knowledge and format practice, so it is a strong core resource. It is not enough on its own for two reasons: its analytics measure within-bank progress rather than readiness against the RCoA standard, and it does not prepare you for the structured oral and OSCE stations that follow the MCQ gateway, which need separate, spoken practice.
Which Primary FRCA component does Pastest not reproduce well? It does not reproduce the oral and OSCE components at all, because those are spoken and clinical assessments no written bank can simulate. Within the MCQ, the physics, clinical-measurement and statistics area is the one trainees most often under-practise, and any single bank can under-sample sub-topics, so verify coverage against the blueprint rather than trusting the overall average.
How many Pastest questions should I complete per day for the Primary FRCA? Volume is less important than first-attempt quality and even blueprint coverage. A sustainable target around clinical work is roughly 30 first-attempt questions a day, spread deliberately across all three subject areas, with full review of errors. Chasing a high daily count tends to inflate repeat accuracy through recognition memory rather than building genuine, transferable knowledge.
When should I stop using Pastest and move to mixed mocks? Move to timed mixed blocks once your first-attempt accuracy on unseen material is stable across pharmacology, physiology and the physics-measurement-statistics area, rather than when the bank is complete. If your repeat accuracy is high but first-attempt performance has plateaued, that is the signal to stop drilling familiar items and start simulating the real, mixed, three-hour paper.
How should I combine Pastest with iatroX without duplicating practice? Assign each a single job: use Pastest for knowledge and format practice across its bank, and use iatroX only for unseen, timed, mixed blocks you never pre-read, so it remains a clean measurement layer. Keeping the roles distinct follows the two-Q-bank rule, prevents duplicated questions, and protects the unseen items that give you your one honest readiness signal.
