This is a workflow for paediatric trainees who use Pastest for the MRCPCH Foundation of Practice (FOP) paper and want its AI Tutor mode to strengthen their reasoning rather than do it for them. It targets FOP's foundational, decision-focused single-best-answer items. The one limitation to design around is that Pastest does not disclose how Tutor mode is grounded — so the method makes commitment and verification compulsory, and keeps the thinking with you.

The tutor is a genuine AI assistant, but the absence of a disclosed model or grounding is why this workflow treats it as a prompt-driven explainer whose outputs you check — never as the source of the answer.
The FOP exam anchor
FOP is the first written MRCPCH stage, usually taken alongside Theory and Science: 100 single-best-answer questions in two hours, one paper, computer-based, no negative marking — so you answer every item, guessing where you must — at about 72 seconds an item. It tests knowledge, understanding and clinical decision-making at entry to core paediatric training and is more foundational than the data-heavy AKP, though vignettes and single-decision judgement dominate. The syllabus is broad, spanning neonatology, cardiology, respiratory medicine, gastroenterology, neurology and neurodevelopment, infection, endocrinology and haematology, with the cross-cutting themes of safeguarding, patient safety, ethics and pharmacology. The RCPCH publishes the syllabus and official example questions that define the standard. Because the pace is tight and the reasoning is yours to do on the day, the goal is a tutor that trains judgement, not one that supplies it.
Why outsourcing your reasoning is the real risk
The danger with any capable tutor is not that it is wrong — it is that it is convenient. If you open it before you have thought, it will reason for you, and the recall and decision-making FOP actually tests never get exercised. A trainee who reads the tutor's breakdown of a collapsed-infant vignette before committing will recognise the same item next week, but will not have rehearsed the timed judgement the paper demands. Recognition then inflates your percentage while your independent reasoning stalls, which is precisely why a bank percentage is not your exam score. Every rule below exists to keep the cognitive work on your side of the screen.
The prompt taxonomy: six jobs for the tutor
Open the tutor with one defined job: mechanism, discriminating features, option elimination, guideline verification, counterfactuals, or retrieval testing. These six turn the tutor from an answer-dispenser into a sparring partner. The forbidden prompt is "what is the answer?" — it does the one thing the exam will not let you do.
Twenty-five prompts, grouped by the six commonest error types
Fill the brackets with your own item; keep prompts generic and never paste proprietary question text.
Error type 1 — Knowledge gap
- "Explain the core mechanism behind [finding] in one short paragraph, as if teaching a medical student."
- "What is the classic presentation of [condition] in children?"
- "Give the single most important cause I must not miss for [presentation] at this age."
- "State the normal developmental milestone for [domain] at this age."
Error type 2 — Discriminator miss 5. "What one feature separates [A] from [B] on history alone?" 6. "Contrast [A] and [B] in a two-row table: typical age, key feature, first test." 7. "Which detail in a stem should make me switch from the obvious answer to the correct one?" 8. "Why is the popular wrong answer tempting here, and what rules it out?"
Error type 3 — Guideline or currency error 9. "Which UK source (NICE, CKS, SIGN, RCPCH or NHS) defines this answer, and when was it last updated?" 10. "Is this immunisation or screening item consistent with the current UK schedule?" 11. "Has advice on [topic] changed recently? Give the old and the current position." 12. "For any drug named, what does the SmPC/eMC state — do not rely on memory for the dose."
Error type 4 — Reasoning or decision error 13. "Show the reasoning chain from presenting complaint to best answer, one step per line." 14. "What is the single decision this item hinges on?" 15. "If the stem is ambiguous, state the safest interpretation and why." 16. "What piece of information, if added, would flip the answer?"
Error type 5 — Management or next-step error 17. "What is the immediate next step versus the definitive management here?" 18. "What must be excluded before I choose this management?" 19. "Which option is correct medicine but wrong for a first-line, entry-level answer?" 20. "What is the appropriate escalation or referral, and its threshold?"
Error type 6 — Careless or process error 21. "Point to the exact word in the stem that fixes the answer." 22. "Kill the wrong options one by one and name the rule behind each." 23. "Is this a recall item or a judgement item? Answer in one word, then justify." 24. "Give me a 45-second strategy for choosing between two close options under time pressure." 25. "Rephrase the question so a colleague could answer it without seeing the options."
The anti-answer-leak rule
Commit in writing to your option and a one-line rationale before Tutor mode opens. This single rule is what keeps your reasoning yours: it forces the retrieval and judgement FOP examines, and it gives you a prediction to test the explanation against. No commitment, no tutor — every time.
The jurisdiction-and-date check
For any management, dosing or threshold answer, reuse this prompt: "State whether this reflects current UK paediatric practice for the MRCPCH, name the specific NICE, CKS, SIGN, SmPC/eMC or RCPCH source, and give its date; if you cannot, say so." No dated UK source means no verified answer. This matters most for immunisation schedules, resuscitation steps and drug doses, where non-UK or out-of-date values are the usual trap.
The misconception record
Every real miss earns four lines: the incorrect rule you held, the corrected rule with its source, a transfer question testing the same idea differently, and a review date three to seven days ahead. That turns a wrong answer into scheduled, checkable learning rather than a vague sense that a topic is shaky.
The weekly verification sample
Once a week, re-check five to ten accepted tutor answers against official or primary sources and log any discrepancy — what the tutor said, what the source says, and the correction. Recurrent discrepancies are your cue to tighten verification and trust the default output less; the habit is the same calibration discipline we recommend before you rely on any AI-graded feedback.
Worked example: seven days around the rota
Pastest teaches; iatroX measures on unseen, timed items. No claims are made about either platform's internals.
- Monday (25 min): 20 Pastest FOP items, tutor off; flag misses.
- Tuesday (35 min): rework misses with the prompt taxonomy; write a misconception record for each; run the jurisdiction-and-date check on management items.
- Wednesday (20 min): one microlearning video on your weakest domain; draft three retrieval questions.
- Thursday (35 min): fresh 30-item Pastest set in your two weakest areas.
- Friday (25 min): 20 unseen, timed iatroX items, no assistance; first-attempt accuracy only.
- Saturday (15 min): weekly verification sample; re-test due misconception records.
- Sunday: rest, or a timed 100-item mock near the exam.
Two banks, two jobs — the two-Q-bank rule. iatroX's free UK-core banks measure transfer without duplicating your Pastest questions.
Decision checklist: continue, supplement, switch or stop
- Continue while unseen first-attempt accuracy climbs and misconception records close on time.
- Supplement with an independent measurement bank if your Pastest percentage outpaces your unseen score.
- Switch only for a measured, recurring coverage gap.
- Stop anything that has not shifted your unseen score in two honest weeks.
Frequently asked questions
Is Pastest enough for MRCPCH Foundation of Practice on its own? As a primary learning bank it is broadly sufficient for most candidates — 1,396 FOP-specific questions with explanations and five past papers (vendor-reported, 19 July 2026). This workflow supplies what it cannot: verified rework and unseen, timed measurement that proves the learning transfers to a fresh paper.
Which MRCPCH Foundation of Practice component does Pastest not reproduce well? The untimed Tutor mode cannot reproduce 100 timed, mixed items in two hours. Learn in Pastest; rehearse the timed, unassisted paper separately so pace and recall are tested together.
How should I verify Pastest AI answers for MRCPCH Foundation of Practice? Commit first, run the jurisdiction-and-date prompt, then confirm against NICE, CKS, SIGN, the SmPC/eMC or the RCPCH example questions. Any unsourced answer is provisional; capture real discrepancies in the weekly verification sample.
When should I stop using Pastest and move to mixed mocks? When fresh-set accuracy plateaus and errors stop clustering, move to full-length, timed, mixed mocks — usually the last three to four weeks before the diet.
How should I combine Pastest with iatroX without duplicating practice? Assign roles, not repeat questions: Pastest for drilling and AI rework, iatroX for unseen, timed, unassisted measurement read on first-attempt accuracy. That is the two-Q-bank rule, and it keeps recognition from masquerading as readiness.
