The Six FRCR 2A Modules and How to Balance Your Revision

What you are actually being tested on
The FRCR 2A can feel huge at first glance. The whole of radiology, squeezed into a couple of papers, with single best answer questions coming at you from every direction. The good news is that the exam is built around six clear modules. Once you know them, you can plan your revision properly instead of just reading whatever happens to be on top of the pile.
Let me walk you through the six modules and, more importantly, how to share your time between them so nothing gets neglected.
The six modules
The Royal College splits the syllabus into six areas. They are:
- Cardiothoracic and vascular (chest, heart, great vessels and peripheral vasculature)
- Musculoskeletal and trauma (bones, joints, soft tissues and the trauma you will meet on call)
- Gastrointestinal (the gut, plus the solid organs of the abdomen)
- Genitourinary, adrenal, obstetrics and gynaecology, and breast (a big mixed bag)
- Paediatrics (everything from neonatal chests to non-accidental injury)
- Central nervous system and head and neck (brain, spine, and the tricky anatomy of the head and neck)
Notice that some modules cover one neat system and others bundle several together. That matters when you plan, because the broad modules quietly carry a lot of content.
Why balance matters more than you think
Most trainees have a comfort zone. Maybe you love chest films and find neuro a bit frightening. The natural temptation is to keep revising the thing you already enjoy, because it feels productive and your scores look healthy.
The exam does not reward that. It samples across all six modules, so a glaring weakness in one area can drag down an otherwise strong performance. A balanced candidate who is solid everywhere usually beats a spiky candidate who is brilliant at two modules and shaky on the rest.
So the aim is not to be perfect at your favourite topic. It is to lift your weakest modules up to a safe, passing standard.
How to split your time
Here is a simple approach that works for most people.
Start with an honest baseline
Before you plan anything, find out where you actually stand. Do a mixed set of questions across all six modules and look at the breakdown. You will often be surprised. The module you assumed was fine might be your weakest, and the scary one might be better than you feared.
This is where a good question bank earns its keep. The per-module performance tracking on SmashRad shows you exactly which areas are lagging, so your plan is based on data rather than gut feeling.
Give more time to weaker and broader modules
Once you know your numbers, weight your revision accordingly. The broad modules (that genitourinary and obstetrics bundle, for example) need more hours simply because they cover more ground. Your personal weak spots need extra love too.
A rough starting point: spend a little more time on the two broadest modules and your two lowest-scoring ones, and keep the others ticking over so they do not go rusty.
Rotate, do not silo
Do not spend three solid weeks on neuro and then never touch it again. You will forget most of it by exam day. Instead, rotate through all six modules in cycles. Touch each one regularly, even if only briefly, so the knowledge stays warm. Spaced repetition is your friend here.
Keep your strong module alive
It is tempting to abandon your best area entirely to focus on the weak ones. Resist that. A short weekly top-up keeps your strong module strong and gives you a confidence boost when the harder topics are grinding you down.
A sample weekly rhythm
You do not need anything fancy. Something like this works well:
- Pick two or three modules to focus on each week, mixing one strong and one weak.
- Do a block of questions in each, then read around the ones you got wrong.
- Once a week, do a mixed set across all six modules to keep everything fresh and to track your progress.
- Every few weeks, sit a timed mock so you practise pacing and decision-making under pressure.
The timed element matters. Plenty of trainees know enough to pass but run out of time or panic on the day. Practising under exam conditions fixes that.
Use the two ways of learning
There is a difference between recognising the right answer and being able to recall it cold. Single best answer questions test the first. Bite-size recall questions train the second.
Use both. Work through exam-style single best answer questions to get used to the format and the level of detail, and use a Learning mode of short recall questions to lock down the facts that keep slipping away. SmashRad has both, with full explanations and Radiopaedia links on hand when you want to dig deeper into a topic. The free account gives you 40 sample questions with no card needed, which is plenty to test the waters and see how the module tracking feels.
A few honest reminders
- Anatomy variants and normal appearances come up more than you expect, so do not only revise pathology.
- Paediatrics is small but distinctive, and a little focused effort there pays off nicely.
- Do not let one bad practice score wreck your confidence. It is information, not a verdict.
Balance really is the whole game with the 2A. Know the six modules, find your weak spots early, and keep every area ticking over rather than cramming one and dropping another.
