MRCP Part 1 preparation: the complete revision guide
A practical guide to preparing for MRCP(UK) Part 1: what the exam is, how it is structured and marked, what the syllabus covers, how long candidates typically revise, and a revision strategy built around question practice. Every section links to the detailed Examrix resource for that topic.
What the exam covers
Clinical medicine across all major specialties, tested through best-of-five single-best-answer questions.
Applied basic medical sciences relevant to everyday clinical practice.
Clinical reasoning, mechanisms of disease and interpretation of investigations.
Exam format
Two written papers, each 3 hours long, each with 100 best-of-five questions.
Delivered as a computer-based exam at Pearson VUE test centres.
A pass requires a scaled score above the pass mark set for that diet.
What is MRCP Part 1?
MRCP(UK) Part 1 is the first examination in the Membership of the Royal Colleges of Physicians diploma, run by the Federation of the Royal Colleges of Physicians of the UK. It is a written knowledge test taken by doctors moving from foundation-level practice into internal medicine training, and it is a prerequisite for the later Part 2 written and PACES clinical examinations.
It tests applied knowledge across the whole of general internal medicine rather than one specialty. The questions are clinical: a short case vignette, some investigations, and five plausible options of which one is best. Recall alone is rarely enough — most items require you to interpret data and choose between close differentials.
Eligibility
Part 1 is open to doctors with a minimum of 12 months' postgraduate experience in medical employment. You do not need to be in a UK training post, and there is no requirement to have completed a specific programme.
Eligibility criteria, attempt limits and the time window in which the full diploma must be completed are set by the Federation and are revised periodically. Confirm the current rules — along with application windows and fees — on the Examrix MRCP Part 1 exam dates page before you apply.
Question distribution across specialties
The Part 1 blueprint spreads 200 questions across the medical specialties, with the larger acute specialties carrying more items than the smaller ones. Cardiology, respiratory medicine, gastroenterology, endocrinology, neurology and clinical pharmacology together account for a substantial share of the paper, while dermatology, ophthalmology, psychiatry and the clinical sciences appear in smaller but reliably present numbers.
The practical consequence is that you cannot pass on a few strong specialties. A candidate who is excellent in cardiology and respiratory medicine but repeatedly drops marks across five or six smaller specialties can still fail. Plan coverage first, depth second.
Exam dates and application windows
Part 1 runs three diets a year. Each diet has an application opening date, a hard closing date, an earlier deadline for reasonable adjustments, the exam day itself and a results date several weeks later. Applications outside the published window are not accepted, and the closing date for the next diet sometimes falls before results for the current one are released.
All current diet dates, deadlines, fees and results dates are maintained on the MRCP Part 1 exam dates page, which is the page to check before booking leave or planning a resit.
Pass mark and scoring
There is no fixed percentage pass mark. Each diet is standard-set and scores are equated so that the standard required is comparable between diets: a slightly harder paper does not require a higher raw score. Results are reported as a pass equated score against the standard for that diet, with a breakdown by specialty.
That breakdown is useful whether you pass or fail. It shows which specialties sat below the standard, which is the natural starting point for a resit plan or for Part 2 preparation.
Pass rates: how to read them
The Federation publishes pass-rate data by diet and by candidate group. The headline figure is less useful than the split: first-attempt candidates consistently outperform repeat attempters, and candidates who prepared with structured, broad coverage do better than those who revised selectively.
Treat published pass rates as context for planning rather than as a prediction. Your own timed-block accuracy across the full syllabus is a far better guide to readiness.
How long should you prepare?
For a candidate working a full clinical rota, three to four months of consistent preparation is a reasonable starting point, at roughly 8–12 focused hours a week rising towards the exam. A resit after a near miss may need only six to ten focused weeks; significant gaps or a demanding rota may need four to five months.
The number of weeks matters less than whether the plan leaves room to meet the whole syllabus, do substantial question practice, identify weak specialties, revisit them and finish with timed full-length practice.
A suggested revision strategy
Phase 1 — Coverage
Work through the blueprint specialty by specialty. Read a topic, then immediately do 20–30 questions on it. Aim for exposure across everything rather than mastery of anything, and log your accuracy per topic from the first week so later phases are driven by data rather than instinct.
Phase 2 — Volume
Move to question-led revision in timed blocks. Every wrong answer gets a one-line reason: knowledge gap, misread stem, or guideline detail. That log is worth more than the raw number of questions attempted, because it tells you which errors are fixable by reading and which by slowing down.
Phase 3 — Targeted consolidation
Give dedicated sessions to the topics sitting furthest below your average. Clinical pharmacology, clinical sciences and statistics reward this stage disproportionately, because the facts are discrete, testable and frequently examined.
Phase 4 — Rehearsal
In the final fortnight, sit at least two complete 100-question papers under exam conditions, at the time of day you will actually sit. After that, review only — no new material.
How to use a question bank effectively
Start questions on day one. Using a bank only at the end turns it into an assessment instead of a learning tool.
Read the explanation for every item, including those you answered correctly — a lucky guess and a reasoned answer look identical in your score.
Work in blocks rather than single questions, so you practise sustaining judgement across a paper.
Keep an error log with a reason for each mistake, and re-test those topics rather than re-reading them.
Use per-topic analytics to choose what to revise next, rather than gravitating towards the specialties you enjoy.
Resist repeating the same bank until you recognise stems. Recognition is not knowledge, and it inflates your accuracy.
Mock exams and timed practice
Part 1 is two three-hour papers on the same day. Six hours of best-of-five questions is a stamina task as much as a knowledge one, and candidates who have never sat a full-length paper commonly lose marks in the second half.
Build up through timed blocks to at least two full-length rehearsals. Time your blocks at roughly 1.8 minutes per question, and review the paper the following day rather than immediately, so the review is analytical rather than emotional.
Common reasons candidates underperform
Uneven coverage — several specialties barely touched by the final fortnight.
Passive revision: re-reading notes and highlighting instead of retrieval practice.
Treating the question bank as a test at the end rather than a learning tool from the start.
Skipping explanations for correct answers, so guesses are never converted into knowledge.
Never practising at full length, then fading during the second paper.
Neglecting clinical pharmacology, statistics and the clinical sciences, which are high-yield and quick to fix.
Misreading stems under time pressure — usually a pacing problem, not a knowledge one.
Starting too late relative to a rota, then sitting a diet before the plan has finished.
Exam-day advice
Confirm centre location, travel and ID requirements the week before, not the night before.
Request leave for the exam day as soon as your application is accepted, and swap nights in the fortnight beforehand.
Answer every question — there is no negative marking, so leave nothing blank.
Flag and move on rather than stalling: one difficult item is worth the same as an easy one.
Eat and hydrate properly between papers; the second paper is where fatigue costs marks.
Do not review the first paper's answers with colleagues during the break.
What happens after MRCP Part 1
Passing Part 1 opens the MRCP Part 2 written examination and, in turn, PACES. Most candidates move straight into Part 2 preparation, where the same broad clinical knowledge is tested with longer vignettes and more emphasis on management decisions.
The specialty breakdown on your Part 1 score report is the most useful starting point: the areas that sat closest to the standard are usually the ones to reinforce first, and much of the Part 1 groundwork carries directly into Part 2 and PACES.

Sample MRCP Part 1 questions
Three example single-best-answer questions in the style of the MRCP Part 1 bank, with the reasoning behind the correct answer.
Question 1
A 68-year-old man with heart failure and an eGFR of 28 mL/min/1.73m² is started on a new drug. Two weeks later his potassium is 6.1 mmol/L. Which drug is the most likely cause?
A.Furosemide
B.Spironolactone
C.Bisoprolol
D.Ivabradine
E.Digoxin
Answer: Spironolactone
Mineralocorticoid receptor antagonists block distal tubular sodium–potassium exchange and are a common cause of hyperkalaemia, especially when eGFR is below 30. Furosemide causes hypokalaemia; bisoprolol, ivabradine and digoxin are far less likely to raise potassium to this degree.
Question 2
A 24-year-old woman has fatigue and a haemoglobin of 96 g/L with an MCV of 68 fL, low ferritin and a raised platelet count. Which is the single most appropriate next investigation?
A.Bone marrow aspirate
B.Haemoglobin electrophoresis
C.Coeliac serology
D.Serum B12 and folate
E.Direct antiglobulin test
Answer: Coeliac serology
A microcytic, iron-deficient picture in a young woman warrants a search for a cause. Coeliac disease is a common and readily testable cause of malabsorptive iron deficiency. Electrophoresis is used when ferritin is normal and thalassaemia trait is suspected; marrow sampling is not first line.
Question 3
A 55-year-old man presents with a 3-day history of confusion, and sodium of 116 mmol/L with serum osmolality 245 mOsm/kg, urine osmolality 480 mOsm/kg and urine sodium 55 mmol/L. He is clinically euvolaemic. What is the most likely diagnosis?
A.Syndrome of inappropriate ADH secretion
B.Primary polydipsia
C.Diuretic-induced hyponatraemia
D.Addison's disease
E.Cardiac failure
Answer: Syndrome of inappropriate ADH secretion
Euvolaemic hypotonic hyponatraemia with inappropriately concentrated urine (>100 mOsm/kg) and urine sodium above 30 mmol/L is the classic biochemical signature of SIADH. Primary polydipsia produces dilute urine; hypovolaemic causes give a low urine sodium.
Each of the two papers has 100 best-of-five questions, for 200 questions in total across the exam, sat as two three-hour papers on the same day.
What is the pass mark for MRCP Part 1?
There is no fixed percentage pass mark. Each diet is standard-set and scores are equated so the required standard is comparable between diets, with results reported as a pass equated score plus a specialty breakdown.
How long should I revise for MRCP Part 1?
For a candidate working a full clinical rota, three to four months of consistent revision at around 8–12 focused hours a week is a reasonable plan. A resit after a near miss may need only six to ten focused weeks.
Who is eligible to sit MRCP Part 1?
Doctors with a minimum of 12 months' postgraduate experience in medical employment are eligible. You do not need to be in a UK training post, but you should confirm the current criteria before applying.
How many practice questions should I do for MRCP Part 1?
Most successful candidates work through several thousand best-of-five questions, reviewing every explanation — including for items answered correctly — rather than chasing raw question counts.
Is there negative marking in MRCP Part 1?
No. Marks are not deducted for wrong answers, so you should attempt every question rather than leaving any blank.
