MRCP Part 1 Question Strategy: Best-of-Five Technique
A repeatable way to interpret MRCP Part 1 stems, separate plausible options and manage time across each paper.
MRCP Part 1 uses best-of-five questions: one preferred answer and four related but less correct alternatives. The Federation's format guide says the format tests interpretation and clinical problem-solving as well as knowledge. Technique helps you apply that knowledge consistently.
Read the task precisely
Start with the final sentence. “Most likely diagnosis”, “best initial investigation” and “next management step” require different answers from the same stem. An option may be true but still answer the wrong question.
Watch qualifiers such as initial, definitive, immediate, most likely and most appropriate.
Compress the stem
Build a one-line summary containing the patient context, time course and decisive findings. This stops colourful but low-value details from dominating the case.
Whenever possible, predict an answer before reading the options. You may not produce the exact wording, but you approach the list with a clinical hypothesis rather than five suggestions competing for attention.
Compare the closest two options
If two answers remain plausible, ask what single feature separates them. Common discriminators include:
- acute versus chronic onset;
- proximal versus distal findings;
- first-line versus rescue treatment;
- stable versus haemodynamically unstable presentation;
- a practical next test versus the definitive test.
Do not settle for “both can occur”. Choose the option that explains the important findings with the fewest extra assumptions.
Avoid invented tricks
If one interpretation fits the stem cleanly, do not invent missing information to defeat it. Change an answer when you identify a concrete error—a missed contraindication, misread value or stronger discriminator—not because the first choice feels too obvious.
Protect time
Each paper allows three hours for 100 questions: an average of 108 seconds per question. Some will take less, leaving time for calculations and difficult stems.
On the first pass:
- answer straightforward questions;
- make the best available choice on harder ones;
- flag questions where more thought could genuinely separate the options;
- move on before one item consumes several questions' time.
There is no negative marking, so answer every question before time expires.
Review the decision that failed
After practice, identify whether the error came from missing knowledge, poor discrimination, misreading the stem or rushing. Write the shortest rule that would change your next decision.
For example: “In an unstable patient, stabilisation comes before the definitive diagnostic pathway.” That is easier to revisit than a copied explanation. Review correct guesses as well as wrong answers.
Six checks before submitting
- What exactly is being asked?
- Which findings are decisive?
- What would I answer without the options?
- Which two options are closest?
- What fact separates them?
- Do I have a clinical reason to change my answer?
