A useful PassPaeds alternative must match the MRCPCH paper you are preparing for. Foundations of Practice and Theory and Science overlap in subject matter, but the learner may need different teaching and practice for each. A generic paediatrics subscription is not automatically the most efficient purchase.
This comparison is published by iatroX and includes its relevant written banks. Public product descriptions were checked on 19 September 2026. The article does not compare examination pass rates or claim official endorsement for any independent provider.
Make the paper visible in the purchase
PassPaeds describes preparation for FOP and TAS. Inspect the package attached to the paper you intend to sit, including question access, explanatory material and duration. Do not infer that a product covers AKP simply because it covers other MRCPCH written examinations.
The RCPCH examination resources provide the official starting point. Use their descriptions and samples to identify the assessment task before choosing an independent learning product.
A learner taking both papers may reasonably want a combined preparation plan. That does not mean every topic should be revised in the same way or that the same weakness will appear in both papers.
Factual recognition and mechanism are different needs
A clinical question may expose uncertainty about the meaning of a finding. A science-focused question may expose a missing mechanism behind it. Both require knowledge, but a learner can recognise the clinical pattern while remaining unable to explain the underlying relationship.
Here is an original educational example. A fictional learner recognises a familiar presentation but cannot explain why a laboratory pattern changes under a different physiological condition. Repeating the original clinical question may strengthen recognition without resolving the mechanism.
The useful next resource could be a diagram, a worked scientific explanation or targeted questioning. Another learner who understands the mechanism but misses the significance of age or context needs a different exercise. The purchase should follow that distinction.
A practical comparison table
| What you need | What to inspect in a sample |
|---|---|
| A scientific explanation | Whether the relationship is derived or merely named |
| Clinical application | Whether the explanation identifies the decisive context |
| Unfamiliar practice | Whether the question requires a fresh decision rather than recognition |
| Help after an error | Whether you can obtain a specific clarification or revisit the concept |
The table is an editorial assessment framework, not a scorecard from testing the providers. Apply it to the exact paper and package you are considering. One well-chosen sample can reveal a useful teaching style, but it cannot establish the quality of an entire bank.
Do not let combined access dictate the timetable
A subscription containing both papers can encourage a learner to divide time equally even when the gaps are unequal. Start instead with the preparation needed for the booked assessment and the topics that require work.
Protect time for explanation and retrieval. A schedule that consists only of new questions may create repeated exposure without a clear correction. After a difficult item, write the principle in your own words and apply it to a changed example. Keep the note short enough to revisit.
The purpose of a second resource should be explicit. It might supply a different explanation of a mechanism or additional questions in an under-covered area. It should not automatically create another complete bank to finish.
When the broader platform earns its place
A learner who wants only paper-specific questions may prefer a specialist bank whose explanations already work well. A learner who repeatedly needs to discuss the reasoning behind an answer may benefit from an integrated Tutor. Someone who needs structured teaching may still prefer a course or a carefully chosen textbook chapter.
These approaches can coexist, but the timetable must remain realistic. Compare how much of each resource you will use before the examination, not how much remains available after purchase.
The verdict
Keep PassPaeds when its FOP or TAS format fits the identified need. Consider iatroX when paper-specific questions, guided reasoning and planning provide a useful alternative. Use official RCPCH material to anchor the assessment, and add teaching selectively when the missing concept is deeper than another answer explanation can resolve.
What iatroX adds to this decision
For MRCPCH FOP and TAS, iatroX's September 2026 product brief describes adaptive questions, spaced review and a Socratic Tutor that works from an attempted answer. The Tutor asks targeted follow-ups to explore the learner's misconception; it is a learning design, not proof that every generated response is correct.
The free-question sample offers up to twenty questions for the selected examination, subject to availability, without an account or card. Full MRCPCH FOP and TAS access and ongoing Tutor use are paid; the separate introductory Tutor session requires a free account.
The UK price published on 19 September 2026 is £99 paid upfront annually, equivalent to £8.25 a month billed annually, or £29 monthly. Paid question banks, Socratic Tutor, the study planner, simulations and CPD tools are included together, not sold as separate simulation or CPD add-ons.
Frequently asked questions
Does FOP and TAS access automatically include AKP?
No. Check the exact package and examination coverage instead of inferring entitlement from the MRCPCH name.
Should I divide revision time equally between the papers?
Not automatically. Allocate time according to the assessment dates and demonstrated learning gaps.
Is a broad paediatrics resource always a better purchase?
No. A specialist paper-specific resource may be sufficient, particularly when you already understand its explanations.
