How I Structure My MRCS Part B Surgical Pathology Revision

May 2026 · 7 min read · Dr. Ali Heidari

Surgical pathology is one of the most content-heavy sections of the MRCS Part B. With 22 major topics spanning cellular pathology, inflammation, neoplasia, immunology, microbiology, and haematology, it can feel overwhelming. Here is the system I developed to make it manageable, visual, and genuinely memorable.

I spent the first week of my pathology revision doing nothing but these four foundational concepts. By the end, every subsequent topic had a logical place to attach to.

Use visual systems, not dense notes

Traditional note-taking in surgical pathology is inefficient for exam revision. I moved entirely to visual diagrams: flowcharts for disease progression, comparison tables for differentials, and illustrated summaries for each major condition. A single comparison diagram of Crohn's versus ulcerative colitis replaced three pages of notes and was far more memorable.

MRCS High-Yield Pearl

In surgical pathology OSCE stations, examiners frequently ask about the molecular basis of conditions. Understanding oncogenes (KRAS in colorectal cancer), tumour suppressor genes (p53, APC), and DNA repair mechanisms is non-negotiable for a high mark.

The spaced repetition approach

I divided the 22 pathology topics into three tiers based on exam frequency. Tier 1 topics I revised every three days. Tier 2 every week. Tier 3 every two weeks. This system dramatically reduced cognitive load and told me exactly what to study each day.

Integrate pathology with anatomy and clinical practice

The MRCS Part B is an integrated exam. When studying colorectal neoplasia, simultaneously review the anatomy of the colon, the clinical staging systems, and the surgical approaches. This integration separates a pass from a high score. Everything in this system is built into SurgAtlas — free for all candidates.
