How the FRCR Part 2A Is Marked and What Score You Need to Pass

The exam in a nutshell

The FRCR Part 2A is a written exam made up of single best answer (SBA) questions. You sit two papers on the same day, and between them they cover all six modules of radiology: cardiothoracic and gastrointestinal, musculoskeletal and trauma, paediatric, central nervous and head and neck, genitourinary, adrenal, obstetrics and gynaecology and breast, and finally the catch-all of nuclear medicine which is integrated in all six modules where relevant.

Each question gives you a stem and five options. One answer is the best. There is no negative marking, so a blank answer and a wrong answer score exactly the same: nothing. Remember that, because it changes how you should behave on the day.

How the marking actually works

Every correct answer earns you one mark. There is no clever weighting, no bonus for harder questions, and no penalty for guessing. Your raw score is simply the number of questions you got right across both papers.

That raw score is then compared against a pass mark. The important thing to understand is that the pass mark is not a fixed percentage that stays the same forever. It is set using a standard-setting method, which means it can shift slightly from one sitting to the next depending on how difficult the questions are judged to be.

What is standard setting?

Standing setting is how the Royal College keeps the exam fair across different papers. If one sitting happens to contain a batch of trickier questions, it would be unfair to demand the same raw score as a sitting with easier questions. So a panel of experienced radiologists reviews each question and estimates how a borderline candidate (someone who is just about good enough to pass) would perform on it.

Add those estimates together and you get the pass mark for that paper. A harder paper produces a slightly lower pass mark. An easier paper produces a slightly higher one. The aim is that the standard of knowledge required to pass stays constant, even when the difficulty of the questions does not.

This is why you should not chase a magic number like "I need 70 percent". The figure moves. What stays the same is the level of competence expected of you.

So what score do you actually need?

In practice, the pass mark tends to sit somewhere in the region of the high sixties to low seventies as a percentage, though it genuinely varies by sitting. Do not treat that as a guarantee. Treat it as a rough target to aim above.

A sensible working goal is this: if you are consistently scoring comfortably above 75 percent on good quality practice questions, you are giving yourself a healthy buffer. Aiming only for the bare pass mark is risky, because exam nerves, a tricky paper, or a few unlucky topics can pull you down on the day.

You will be told your result as a pass or fail, and you usually get feedback on your performance by module. That module breakdown is gold. It tells you where you were strong and where you were exposed, which matters if you ever need to resit.

What this means for your revision

Knowing how the marking works should change how you prepare. A few practical takeaways:

• Cover everything. Because the pass mark is built from across all modules, you cannot afford a complete blind spot. A weak module drags your raw score down with no way to compensate elsewhere beyond your overall total.
• Answer every question. No negative marking means a guess is free. Never leave a blank. Even an educated stab at two remaining options gives you a 50 percent chance of a mark you would otherwise lose.
• Build a buffer. Aim higher than the likely pass mark so a hard paper does not sink you.
• Train under time pressure. Both papers are tightly timed. Knowing the answer slowly is not the same as knowing it quickly.
• Use your weakest areas to guide revision. If practice tells you your physics or paediatrics is shaky, that is exactly where extra marks are hiding.

How to know if you are ready

The honest answer is that you cannot judge readiness by reading textbooks. You judge it by doing questions, lots of them, and watching your scores over time. The exam is an SBA test, so the most realistic preparation is practising SBAs in the same format.

This is where a focused question bank earns its keep. SmashRad has over 12,000 exam-style single best answer questions with full explanations and Radiopaedia links, so when you get something wrong you actually learn why. There is a separate Learning mode of bite-size recall questions for quick reinforcement, plus timed mock exams that mimic the pressure of the real thing.

The per-module performance tracking is particularly useful for this exam. Because your fate depends on covering every module, seeing your scores broken down by topic shows you precisely where to spend your next study hour. The revision recommendations then point you towards your weak spots rather than letting you rehearse what you already know.

The takeaway

The FRCR Part 2A is marked simply: one mark per correct answer, no penalties, and a pass mark set by standard setting so the difficulty stays fair across sittings. You do not need a fixed percentage in your head. You need broad, solid knowledge across all six modules, the discipline to answer every question, and enough practice that a tricky paper does not catch you out.

Get your scores comfortably above the likely pass mark in realistic conditions, and the actual exam becomes far less daunting.
