MRCP Part 1 has the lowest pass rate of any major UK postgraduate written exam. Approximately half of all candidates fail on their first attempt. The exam consists of two papers, each lasting three hours, with 100 best-of-five questions per paper. It tests knowledge across the entire breadth of internal medicine, including basic sciences, clinical pharmacology, and clinical medicine across every organ system and specialty.
The difficulty is not in the obscurity of the questions — it is in the breadth. MRCP Part 1 tests topics from dermatology to genetics, from tropical medicine to psychiatry, from statistics to clinical pharmacology. No one feels fully prepared. The goal is not to know everything; it is to know enough across enough topics to pass.
This guide covers the approach, the timeline, the resources, and the specific strategies that distinguish candidates who pass from those who do not.
The Approach That Works
MRCP Part 1 is a Q-bank exam. The candidates who pass are the candidates who do the most questions and review the most explanations. Passive reading — working through Kumar and Clark or the Oxford Handbook chapter by chapter — is not sufficient. Active retrieval practice (answering questions, getting them wrong, reading the explanation, and revisiting the topic) is the evidence-based approach that produces results.
This does not mean you should abandon textbooks entirely. It means the Q-bank is your primary tool, and textbooks are your reference when you need deeper understanding of a topic that questions have exposed as a weakness.
The optimal ratio for most candidates is roughly 70% Q-bank practice and 30% targeted reading. As the exam approaches, the ratio should shift further toward questions — 90% Q-bank in the final two weeks.
The Timeline
Most successful candidates prepare over 3–6 months, depending on how much time they can dedicate daily alongside clinical work. A realistic plan for a working junior doctor allocates 2–3 hours per day, six days per week.
Months 1–2: First Pass
Work through your primary Q-bank systematically. Do 50–80 questions per day in revision mode (untimed, with explanations visible). Cover all topic areas. Do not skip topics you find boring or difficult — these are often the topics that appear on the exam precisely because candidates neglect them.
Flag every question you get wrong or are uncertain about. Read the explanation carefully. For topics where the explanation is not sufficient, refer to your textbook or use iatroX's clinical AI to query the underlying guideline or mechanism.
By the end of month 2, you should have completed a full first pass through your Q-bank. Your overall score at this stage is typically 50–60%. This is normal and expected.
Months 3–4: Targeted Second Pass
This is where the exam is won or lost. Use your first-pass data to identify your weakest topics. Most Q-banks provide performance analytics by topic — use them.
Do a targeted second pass focusing on your weak areas. If your endocrinology score is 45% but your cardiology score is 72%, spend three times as much time on endocrinology. Do not spend equal time on all topics — this is the most common strategic error.
This is also where adaptive Q-banks add genuine value. iatroX's adaptive mode automatically identifies your weakest topics and prioritises them in your question selection. The spaced repetition algorithm schedules reviews of previously incorrect questions at optimal intervals. If you are using a traditional Q-bank like PassMedicine, you will need to manually filter by weak topics and create custom tests — it works, but it requires more self-discipline.
Months 5–6: Mock Exams and Consolidation
Do at least three full-length mock exams under strict timed conditions. Each mock should be 200 questions in 6 hours (simulating both papers back-to-back with a break). Time yourself rigorously.
Mock exams reveal two things: whether you can maintain concentration over 6 hours (exam stamina is a real factor), and which topics you are still weak on despite two passes. After each mock, do a thorough review of every incorrect answer.
In the final two weeks, focus exclusively on incorrects-only sessions and flagged questions. Do not start any new resources. Consolidate what you know.
Common Failure Areas
Certain topics are consistently under-prepared by MRCP Part 1 candidates.
Clinical pharmacology — mechanism of action, side effects, interactions, and contraindications — accounts for a significant proportion of questions. Many candidates rely on clinical experience for prescribing knowledge and do not formally revise pharmacology. This is a mistake.
Basic sciences — genetics, immunology, cell biology, and molecular medicine — appear more frequently in MRCP Part 1 than in any other UK postgraduate exam. These topics require dedicated revision time.
Tropical medicine and infectious diseases — candidates who have not worked in tropical medicine often neglect this area. It is testable and does appear.
Statistics and evidence-based medicine — a smaller proportion than in the AKT, but still present. Know the basics: sensitivity, specificity, study design hierarchy, NNT.
Dermatology and ophthalmology — image-based questions from these specialties catch candidates who have not practised visual pattern recognition.
The Resources
PassMedicine — Market Leader
PassMedicine offers 5,100+ MRCP Part 1 questions and remains the resource used by the majority of UK MRCP candidates. The Knowledge Tutor textbook is integrated with questions, providing revision context beyond explanations. The community comment threads are legendary — thousands of candidates sharing mnemonics, clinical pearls, and debates about controversial answers.
Pricing is typically £35 for 4 months — the best value-per-question in the market.
PassMedicine's limitation is that it does not adapt to your performance. You choose what to study. If you lack self-discipline in targeting weak areas, you may spend too much time on comfortable topics and too little on weak ones.

Pastest — Premium with Multimedia
Pastest offers a large MRCP Part 1 bank with tailored past papers reflecting recent exam themes, video and podcast content, a searchable textbook, and an AI tutor for question clarification. Pricing ranges from approximately £95 for 3 months to £180 for 12 months.
Pastest is strongest for candidates who benefit from multimedia learning and who want past-paper-style practice. The AI tutor is useful when explanations do not make sense — you can ask follow-up questions in real time.
Quesmed — All-in-One Hub
Quesmed covers MRCP alongside UKMLA, MSRA, and UCAT in a single subscription. The integrated knowledge library and flashcards provide a complete learning ecosystem. Strong mobile app with offline support. From approximately £14.99 per month.
BMJ OnExamination — Check Your Trust
BMJ OnExamination offers an MRCP Part 1 module within its broader exam platform. Many NHS Trusts provide free BMJ OnExamination access through their library subscriptions. Before paying for any MRCP resource, check whether your Trust offers this — it can save over £100.
iMedics — Free Tier
iMedics offers a free MRCP Part 1 tier with limited questions and paid upgrades. Useful for trying before buying. Also covers PLAB, UKMLA, MSRA, and other exams.

iatroX — Free Adaptive
iatroX offers a free MRCP Part 1 Q-bank with AI-powered adaptive learning. The algorithm identifies weak topics from your performance data and prioritises them automatically. Spaced repetition schedules reviews at optimal intervals for long-term retention.
The integrated clinical AI lets you explore the mechanism or guideline behind a question in seconds — useful when a Q-bank explanation does not go deep enough. The platform also covers MRCP Part 2, AKT, MSRA, PLAB, UKMLA, and MRCEM at no additional cost.
iatroX is UKCA-marked and MHRA-registered as a Class I medical device.
The Optimal Stack
For most MRCP Part 1 candidates, the strongest preparation combines two elements.
A high-volume primary Q-bank: PassMedicine (best value and volume) or Pastest (premium with multimedia).
A free adaptive supplement for weak-area targeting: iatroX (AI-adaptive, spaced repetition, clinical AI for guideline lookup).
This combination gives you the breadth of a large traditional Q-bank and the efficiency of adaptive targeting — covering both pillars of effective MRCP Part 1 preparation.
After Part 1
Passing MRCP Part 1 opens the door to MRCP Part 2 Written and then PACES. The clinical knowledge you build for Part 1 carries forward, but Part 2 tests at a higher level of clinical decision-making, and PACES tests bedside clinical skills. iatroX covers MRCP Part 2 as well, so your adaptive progress and identified weak areas carry forward to the next exam.
