MRCS Part A Question Bank
A focused MRCS Part A question bank: 3,300+ single best answer (SBA) questions with detailed anatomical and clinical explanations, built for the Applied Basic Science and Principles of Surgery in General papers.
What the MRCS Part A question bank covers
MRCS Part A tests knowledge in two papers: Applied Basic Science and Principles of Surgery in General. The PassMRCS bank is organised the same way, so you can target weak areas instead of working through questions at random.
- Surgical anatomy - head and neck, thorax, abdomen and pelvis, limbs, neuroanatomy, embryology.
- Physiology and biochemistry - fluid and electrolytes, acid-base, endocrine, cardiovascular and respiratory physiology.
- Pathology - inflammation, neoplasia, wound healing, haematology, immunology.
- Microbiology and pharmacology - antibiotics, surgical infection, anaesthetic and analgesic drugs.
- Perioperative care, trauma and critical care - ATLS principles, shock, sepsis, nutrition, ethics and consent.
How the Qbank helps you learn

Frequently asked questions
How many questions are in the PassMRCS Part A question bank?
The bank contains 3,300+ SBA questions, each with an explanation covering why the best answer is correct and why the others are not.
Can I sit timed mock exams?
Yes. Mock Exam Mode simulates exam conditions, while Practice Mode shows the explanation straight after each answer. You can also flag questions and review the ones you got wrong.
What is the MRCS Part A pass mark?
There is no fixed percentage. A panel sets it after each exam using an Angoff benchmark and marker questions, so it varies between sittings. See our MRCS FAQ for details.
Does it work on mobile?
Yes. PassMRCS runs in any modern browser on phones, tablets and laptops, and your progress is saved to your account.
