Best MRCOG Question Banks Compared (2026): Which One Should You Use?
Choosing the right question bank is one of the most important decisions you will make in your MRCOG preparation. A good question bank does not just test you. It teaches you. A bad one wastes your time with outdated recalls and poor explanations. Here is an honest, detailed comparison of every MRCOG question bank available in 2026.
What Makes a Good MRCOG Question Bank?
Before comparing platforms, let us establish what actually matters:
- Question quality over quantity: 500 excellent questions beat 10,000 poor ones. Each question should test clinical reasoning, not just recall.
- Guideline-grounded explanations: every explanation should cite specific RCOG Green-top Guidelines or NICE guidance, not vague textbook references.
- Original content: questions written from current published guidelines, not reconstructed from someone's memory of a past sitting. Reconstructions drift from the source and date badly.
- Spaced repetition: the science is clear: spaced review dramatically improves long-term retention compared to massed practice.
- Performance analytics: you need to know which topics you are weak in, not just your overall score.
The Major Platforms
MasterMRCOG
The largest MRCOG question bank by volume, with over 9,000 questions covering Part 1, Part 2, and Part 3. Much of that content has been accumulated since 2012, so coverage is broad but not uniformly current against today's guidelines. The platform lacks AI features, spaced repetition, or adaptive learning. The interface is functional but dated.
CrashMRCOG
Similar to MasterMRCOG, CrashMRCOG offers 10,000+ questions, primarily recall-based spanning 10 years. The platform focuses on Part 1 and Part 2, with a traditional question-and-answer format. No AI tutoring, no spaced repetition. Useful for volume practice, but with the same recall-related caveats.
PassMRCOG
A more modern platform with 2,000+ questions across Part 1 and Part 2. PassMRCOG stands out for its performance histograms that let you compare your scores against other candidates, and it offers a basic PWA (Progressive Web App) for mobile use. However, it lacks AI-powered features and true spaced repetition.
MRCOG Prep
One of the few platforms to incorporate AI, offering AI-generated study plans. With 5,000+ questions and a subscription model, it positions itself as a modern alternative. However, the AI features are basic recommendation engines rather than true adaptive learning or AI tutoring.
MRCOG AI
Full disclosure: this is our platform. MRCOG AI takes a fundamentally different approach. Every question is written from scratch against current guidance, every explanation is grounded in RCOG and NICE guidelines via AI-powered retrieval, and the platform uses the FSRS spaced repetition algorithm (the same one powering Anki 23.10+). The AI tutor provides Socratic dialogue on any question, and the platform works offline as a Progressive Web App. Clinically reviewed by NHS obstetricians and gynaecologists, for doctors preparing for these exams.
Feature Comparison
When choosing a platform, consider: Do you want volume (MasterMRCOG, CrashMRCOG), peer comparison (PassMRCOG), basic AI (MRCOG Prep), or adaptive AI with spaced repetition and original content (MRCOG AI)? The right choice depends on your learning style and how much time you have before the exam.
Our Recommendation
Use one primary question bank for structured study with spaced repetition, and optionally supplement with a second for volume practice closer to the exam. Whatever you choose, check that its explanations cite the guideline they came from: that is what tells you the content still reflects current RCOG guidance.
