Frequently Asked Questions

Everything you need to know about FRCR Part 1 Physics preparation

What is the FRCR Part 1 Physics exam format?

The FRCR Part 1 Physics exam consists of 200 True/False questions arranged in 40 stems with 5 questions each. You have 2 hours (120 minutes) to complete the exam. The exam covers medical imaging physics including X-ray, CT, MRI, ultrasound, nuclear medicine, and radiation protection.

How many times can I take the FRCR Part 1 Physics exam?

You can attempt the FRCR Part 1 Physics exam a maximum of 6 times. It's important to prepare thoroughly for each attempt as repeated failures may affect your training progression. Most candidates pass within 2-3 attempts with proper preparation.

What is the pass mark for FRCR Part 1 Physics?

The pass mark for FRCR Part 1 Physics is typically around 70%, but this can vary slightly between exam sessions based on the difficulty of questions. The Royal College of Radiologists uses statistical analysis to ensure fair marking standards across different exam periods.

When are FRCR Part 1 exam dates in 2026?

FRCR Part 1 exams are held three times per year in 2026: March 2026, June 2026, and September 2026. Application deadlines are typically 6-8 weeks before each exam sitting. Check the RCR website for exact dates and registration deadlines.

How should I prepare for FRCR Part 1 Physics?

Effective preparation includes: 1) Reading Farr's Physics for Medical Imaging, 2) Practicing 1000+ questions covering all topics, 3) Understanding concepts rather than memorizing, 4) Taking timed mock exams, 5) Focusing on weak areas identified through practice. Allow 3-6 months for comprehensive preparation.

What topics are covered in FRCR Part 1 Physics?

The exam covers: X-ray physics (production, interactions, image formation), CT physics (scanner design, reconstruction), MRI physics (magnetic fields, pulse sequences), Ultrasound physics (wave properties, Doppler), Nuclear medicine (radioactive decay, imaging), Radiation protection (dosimetry, legislation), and Digital imaging principles.

Is FRCR Part 1 Physics difficult?

FRCR Part 1 Physics is challenging but achievable with proper preparation. The pass rate is approximately 70-80% (source: Royal College of Radiologists). Success depends on understanding physics concepts, extensive question practice, and good exam technique. Many candidates find it more challenging than anatomy but manageable with dedicated study.

Can I take Physics and Anatomy exams separately?

Yes, you can take the FRCR Part 1 Physics and Anatomy exams separately or together. Both must be passed to progress to Part 2A. There's no requirement to pass them in the same sitting, allowing you to focus on one subject at a time if preferred.

What resources are best for FRCR Part 1 Physics?

Essential resources include: Farr's Physics for Medical Imaging (primary textbook), online question banks with 1000+ questions, RCR e-learning modules, physics revision courses, and practice exam platforms. Focus on resources with detailed explanations and current exam format.

How long does it take to get FRCR Part 1 results?

FRCR Part 1 results are typically released 4-6 weeks after the exam period ends. Results are sent by email and posted on the RCR candidate portal. If you pass, you can proceed to apply for Part 2A. If unsuccessful, you'll receive a breakdown of performance by topic area.
