MRCPsych Paper A is one of two written papers you need to pass to gain Membership of the Royal College of Psychiatrists, and it's the one most trainees sit first. It tests the scientific and theoretical basis of psychiatry, which is a different skill set from the one you use on the ward. Many trainees are surprised by this. Strong clinical experience helps, but it won't carry you through questions on receptor pharmacology, neuroanatomy and learning theory.
Effective MRCPsych Paper A preparation comes down to two things: a revision plan that matches how the marks are distributed, and practice questions that look like the real paper. Read on to learn our top tips for preparing for MRCPsych Paper A.
What does MRCPsych Paper A test?
Paper A is a single computer-based paper of 150 questions, worth 150 marks, to be completed in three hours. Roughly two-thirds of the questions are multiple choice (MCQs) and one-third are extended matching items (EMIs).
The paper covers five areas of the syllabus, and they aren't weighted equally:
-
Basic neurosciences: 25% (37–38 marks)
-
Clinical psychopharmacology: 25% (37–38 marks)
-
Behavioural science and sociocultural psychiatry: 16.67% (25 marks)
-
Human development: 16.67% (25 marks)
-
Classification and assessment in psychiatry: 16.67% (25 marks)
Given that two subjects (neuroscience and psychopharmacology) account for half of the paper, it’s important to bear this in mind when planning your revision. If your plan treats all five areas equally, it doesn't reflect the exam.
The EMI element matters too. EMIs ask you to match a series of scenarios to the best option from a shared list, so they reward recognition of patterns and distinctions across a topic rather than recall of a single fact. They're worth practising as a format in their own right. For a full breakdown of dates, how to apply and what to expect on the day, read our complete guide to MRCPsych Paper A.
Building your MRCPsych Paper A study timeline
Most candidates who pass first time give themselves at least three to four months of structured MRCPsych Paper A revision alongside clinical work. Less than three months and you're likely to be relying on what you already know, which leaves little room to fix gaps. Much more than six and the early material can fade before the exam.
Because you're working shifts and on-calls, consistency matters more than ambitious targets. Two focused hours on a working day and a longer block on a rest day will serve you better than a daily plan you can't keep up.
Months 1–2: Build the foundations
Start with basic neuroscience and psychopharmacology. They carry the most marks, and for many trainees they're the least familiar. Your energy and motivation are usually highest at the start, so this is the best time to tackle the hard material.
Work through the RCPsych syllabus as a checklist and use a core textbook or revision resource to cover each area in turn. Don't wait until you've "finished" the theory before trying questions. Attempting questions from the first week shows you how the exam frames problems and where your knowledge is thinner than you thought.
Months 3–4: Add depth and cover the rest
By now you'll want to have covered the remaining three domains: behavioural science, human development, and classification and assessment. Move to mixed blocks of questions so that you're switching between topics, as you will in the exam. Spend as long reviewing explanations as you do answering questions. A wrong answer is useful only if you work out why it was wrong.
Start a running list of the errors you keep making. "Didn't know it" isn't specific enough. Try to separate knowledge gaps from misread stems and from cases where you narrowed it down to two options and picked the wrong one. Most candidates find a pattern within a few weeks.
Months 5–6: Exam conditions and consolidation
In the final stretch, sit full-length timed papers: 150 questions in three hours, with no notes and no interruptions. That works out at 72 seconds per question. Aim to move at around 65 seconds so you have time at the end to return to anything you flagged.
Resist the urge to start new topics in the last fortnight. Go back over your weakest domains, redo the questions you got wrong, and keep your sleep as regular as your rota allows.
How to revise each Paper A domain
Each area has its own character, so a single revision method won't suit all five.
Basic neurosciences
This covers neuroanatomy, neurophysiology, neurochemistry and genetics. Build a map before you collect detail: learn where things are and what they do, then attach the pathways and transmitters to that structure. Questions often combine them, such as a deficit that points to a location and the neurotransmitter system involved. Drawing pathways from memory is a good test of whether you understand them or have only recognised them.
Clinical psychopharmacology
Avoid learning this as a list of individual drugs. Work through drug classes, and for each one understand the mechanism, the pharmacokinetics, the main adverse effects and the key interactions. Many side effects can be worked out from receptor activity, which is far easier to retain than a memorised table. Expect questions that ask you to reason from a mechanism to an effect, or the reverse.
Behavioural science and sociocultural psychiatry
This includes learning theory, social psychology and the sociocultural influences on mental illness. It's easy to underestimate because the concepts feel intuitive, but exam questions use precise definitions. Make sure you can tell similar terms apart, such as different types of conditioning or attribution. EMIs are well suited to testing exactly these distinctions.
Human development
Revise this chronologically, following the major developmental theories and milestones, and learn who proposed what. Attachment, cognitive and moral development are all fair game, and questions tend to reward candidates who can place a described behaviour at the correct stage.
Classification and assessment
This area covers descriptive psychopathology and how psychiatric disorders are classified and assessed. Focus on definitions and on telling similar phenomena apart. Practise applying them to short clinical descriptions rather than rereading definitions in isolation.
The final two weeks and exam day
Use the last fortnight to consolidate rather than learn anything new:
-
Revisit your list of recurring errors and the questions you've previously got wrong
-
Sit two full timed papers under exam conditions
-
Do a light review of your weakest domains the day after each paper
-
Keep your sleep as regular as you can
On the day, pace yourself, flag anything you're unsure about and move on. There's no negative marking, so make sure no question is left unanswered by the end. Use any spare time to revisit flagged questions, and don't change an answer unless you have a clear reason to.
Common mistakes in MRCPsych Paper A revision
The most frequent mistake is treating Paper A as a clinical exam. Experience on the ward helps with Paper B and the CASC, but the content here is basic science, and it needs dedicated study.
Leaving neuroscience and psychopharmacology until last is a close second. Together they're half the paper, and both take time to build up. Starting them early leaves room to revisit them.
Candidates also tend to drill questions without reviewing them. Working through 2,000 questions and understanding every explanation does more for your score than rushing through 5,000 questions. If you're getting the same type of question wrong twice, go back to the underlying concept before moving on.
Relying on fragmented or out-of-date study materials is another mistake that some candidates make; it can leave gaps you don't discover until the exam. The question bank you use for exam preparation should be mapped to the current syllabus, weight topics as the paper does, and include EMIs as well as MCQs. A bank that leans heavily on one format can leave you underprepared for a third of the paper.
