No, MRCP Part 1 is a linear, fixed-form exam, not computer-adaptive. It is scored using Item Response Theory through a process called equating, which sometimes causes confusion, but the exam is a fixed paper: the questions do not adapt to your performance.
What the MRCP Part 1 format actually is
MRCP Part 1 is two papers of 100 best-of-five questions each, 200 in total, with three hours per paper, sat on the same day, and no negative marking. From 2026 the written papers return to test centres using computer-based testing. Each paper is a fixed set of questions, so everyone sitting that paper faces the same items, unlike an adaptive test that tailors the paper to each candidate.
How the pass mark is really set
MRCP Part 1 gives an overall scaled score, usually between 200 and 800, calculated by equating, a statistical process based on Item Response Theory that adjusts for the difficulty of each paper using anchor questions, alongside Angoff and Hofstee standard-setting. The scaled pass mark applied from 2026/1 is 450, changed from the previous 540. So the raw percentage needed varies by diet while the scaled standard is constant. See how medical exam pass marks are set.
What would be different if it were adaptive
If MRCP Part 1 were adaptive, it would select each question based on your running ability, and every candidate would see a different paper with difficulty rising as they did well, as in the AMC CAT, explained in how computer-adaptive testing works. MRCP Part 1 uses IRT to equate fixed papers, not to adapt them.
How to prepare given the linear format
Because the papers are fixed, put adaptivity into your revision. Target your weak areas and space your practice to retain them, rather than undirected volume. iatroX's adaptive engine surfaces your weakest areas first, with free sample questions at iatroX.
Frequently asked questions
Is MRCP Part 1 adaptive? No. It is a linear, fixed-form exam of two 100-question best-of-five papers. It is IRT-equated, but that is scoring, not adaptive delivery.
What is the MRCP Part 1 pass mark? A scaled score, set at 450 from 2026/1 on a scale where most scores fall between 200 and 800, changed from the previous 540.
Does equating make it adaptive? No. Equating uses IRT to make scores comparable across different fixed papers. It does not change the questions you see based on your answers.
