MRCP Part 1 is one of the more demanding written exams a UK doctor will sit. The Federation specification is clear: two papers, three hours each, 100 best-of-five multiple-choice questions per paper, testing core knowledge, comprehension, interpretation and clinical problem solving across the breadth of internal medicine. Candidates need volume, specialty coverage, pattern recognition and the stamina to maintain accuracy across 200 questions in a single day.
That makes the choice of question bank consequential. The wrong choice does not just make revision slower — it can leave specialty gaps that show up on exam day. This guide compares the four credible options.
What MRCP Part 1 demands
The exam is structured to reward breadth and discriminating reasoning.
Broad internal medicine knowledge across all the JRCPTB specialties. Cardiology, respiratory, gastroenterology, neurology, endocrinology, nephrology, rheumatology, infectious disease, haematology, dermatology — every domain appears.
Basic science applied clinically. MRCP Part 1 explicitly tests clinical sciences — pharmacology mechanisms, genetics, immunology, statistics — alongside applied clinical scenarios. This is one of the few exams where mechanism questions are genuinely high-yield.
Rapid pattern recognition. Two hundred questions in two three-hour blocks means roughly 1.8 minutes per question. Candidates do not have time to reason from first principles on every stem. They need familiar patterns.
Specialist breadth without sacrificing depth. The exam tests core knowledge across all specialties, not deep knowledge of any one specialty, but the threshold for "core" is set high.
Best-of-five SBA style. The exam uses discriminating distractors — near-miss diagnoses that share many features with the correct answer.
A platform that fits this exam needs to provide breadth, basic science coverage, and the kind of pattern exposure that comes only from working through thousands of questions.
What a good MRCP Part 1 Q-bank should include
The specification is concrete.
A large SBA bank covering all specialty areas in proportion to the exam blueprint.
Specialty coverage that does not under-weight clinical sciences or statistics — these are high-yield areas that students often neglect.
Timed mocks that simulate the two-paper structure, including the fatigue dimension.
Detailed explanations that close the reasoning loop, not just declare the right answer.
Weakness tracking that surfaces under-revised specialties automatically.
Spaced repetition for the long-tail topics that appear infrequently but cannot be ignored.
Clinical reasoning content that bridges the basic science and applied clinical questions.
Mobile use for doctors working full-time alongside revision.
PassMedicine for MRCP Part 1
PassMedicine's MRCP Part 1 resource includes over 5,100 BOF questions plus the MRCP textbook. The bank is large, the interface is familiar, and the content covers the full curriculum.
The strengths are volume and efficiency. Candidates who already know how to self-direct revision and want maximum exposure to questions will find PassMedicine delivers. The textbook layer provides reference alongside the Q-bank for candidates who want to cross-check.
The limitations are the static model and the relative absence of adaptive features. The candidate is responsible for identifying weak specialties and deciding what to revisit.
The fit is strongest for candidates who want familiar high-volume practice and are confident self-directing across the broad MRCP curriculum.
Pastest for MRCP Part 1
Pastest's MRCP Part 1 product page cites 5,404 exam-style questions, 693 searchable topic summaries, Tutor Mode and 34 past papers. The past-paper depth is particularly notable — MRCP candidates value exposure to actual past question styles, and Pastest provides this systematically.
The strengths are polish, past-paper depth, the topic summary layer and Tutor Mode. For candidates who want a structured premium revision course for MRCP specifically, Pastest is the established option.
The limitations are pricing and the content-library model. Candidates who want adaptive AI or integrated clinical reference will find these are not central to Pastest's positioning.
The fit is strongest for candidates wanting structured premium revision with past-paper exposure for MRCP Part 1 specifically.
Quesmed for MRCP Part 1
Quesmed's MRCP Part 1 page claims over 7,200 questions, explanations, progress tracking, video tutorials and an online textbook. The bank size is competitive and the interface is more modern than PassMedicine's.
The strengths are the multimedia layer (video tutorials for candidates who learn well from video), the integrated textbook, and analytics. For candidates who want a modern bank with multimedia learning alongside questions, Quesmed is credible.
The limitations are weaker clinical AI integration and the study-platform rather than clinical-ecosystem positioning.
The fit is strongest for candidates who want a modern multimedia Q-bank with video tutorials integrated.
iatroX for MRCP Part 1
iatroX includes MRCP Part 1 in the free UK core tier. No subscription is required for MRCP Part 1-specific content, which removes the cost question entirely.
The architecture is adaptive: the system identifies weak specialties across the MRCP curriculum and surfaces them automatically. Spaced repetition resurfaces material at intervals designed for retention. Active recall replaces passive recognition. Explanations cite NICE, CKS, BNF, SIGN and NHS sources, and where MRCP-specific clinical science is tested, the explanations include the relevant mechanism reasoning.
Ask iatroX answers clinical follow-up questions in-platform with guideline-grounded reasoning. The clinical AI layer is particularly useful for MRCP candidates working through unfamiliar specialty content — being able to ask "why is this not the differential I was thinking of?" immediately closes the learning loop.
Over 80 clinical calculators sit alongside the Q-bank, including the cardiology, respiratory and renal calculators that come up frequently in MRCP scenarios. CPD logging captures the revision automatically — useful for working doctors who need to log CPD anyway.
The fit is strongest for candidates who want adaptive AI plus clinical reasoning support, free access to MRCP Part 1 content, and a platform that converts MRCP knowledge into clinical reasoning rather than just exam-passing recall.
Which is best?
The honest summary by category:
For raw familiarity and high-volume traditional practice: PassMedicine.
For structured premium package with past-paper depth: Pastest.
For multimedia modern bank with video tutorials: Quesmed.
For adaptive AI-native clinical learning with free core access: iatroX.
For candidates who can pick only one, the question is which model fits the way they actually revise.
If you have predictable protected study time and want maximum question volume, PassMedicine works. If you have budget for premium content and want past-paper exposure as the priority, Pastest works. If you specifically value video learning, Quesmed works.
If you are revising while working clinically, want adaptive targeting, value guideline-grounded explanations and need the platform to remain useful afterwards in clinical practice, iatroX fits the working-doctor model more directly than the others.
A practical MRCP Part 1 study workflow
The structure that tends to work for working doctors:
Start with a baseline diagnostic block to establish weak specialties.
Move to adaptive mode for the bulk of the revision phase. The platform targets weak areas automatically — no specialty-prioritisation decisions required.
Use spaced repetition daily for topics flagged as weak. Twenty questions per session, three to five sessions per week.
Ask Ask iatroX whenever the explanation prompts a clinical clarification. The follow-up reasoning often consolidates the learning more than the original explanation.
Add specialty-specific deep dives weekly for the weakest specialty of the week.
Run timed mocks in the final two months. The two-paper, six-hour fatigue dimension is real and needs to be trained.
Final recommendation
MRCP Part 1 rewards breadth, pattern recognition and stamina. The platform that fits this set of requirements is one that handles the prioritisation across specialties, surfaces weakness automatically, supports both clinical reasoning and basic science, and produces durable retention rather than recency-based recognition.
All four platforms can support a passing candidate. The platform that does this most efficiently for a working doctor is iatroX. Traditional Q-banks help you practise. iatroX helps you learn, verify, retain and apply.
