The British Physics Olympiad (BPhO) is the United Kingdom's premier physics competition for pre-university students. Organized by the BPhO Committee based at the University of Oxford and supported by the Institute of Physics (IOP), the competition has been inspiring and challenging the brightest young physicists since its establishment. Beyond its domestic prestige, the BPhO serves as the selection pathway for the UK national team that competes at the International Physics Olympiad (IPhO) — one of the most prestigious science competitions for high school students worldwide.
What Is the British Physics Olympiad?
The BPhO is an annual series of physics challenges designed to test students' deep understanding of physics principles, creative problem-solving abilities, and mathematical reasoning. Unlike standard school examinations, BPhO problems are known for being intellectually demanding, often requiring students to apply concepts in novel and unexpected ways. The questions go beyond the standard A-level or Higher syllabus, touching on university-level topics and demanding a level of rigor that sets them apart from typical exam papers.
Each year, thousands of students from schools and colleges across the UK — and increasingly from international centres — participate in the various rounds of the competition. The BPhO is recognized by top universities as a mark of exceptional ability in physics and is highly regarded by admissions tutors at institutions such as Oxford, Cambridge, and Imperial College London.
Competition Structure: From School to International Stage
The BPhO follows a carefully designed multi-stage pipeline that progressively identifies and nurtures the most talented young physicists:
1. The AS Challenge (Round 0)
Targeted at students in Year 12 (or equivalent, such as AS-level students), the AS Challenge serves as an accessible introduction to Olympiad-style physics. It is typically held in January or February and provides younger students with an opportunity to experience challenging, non-standard physics problems before they attempt the senior competition. This round is excellent preparation for those aiming to compete in the main BPhO Challenge the following year.
2. BPhO Round 1 (The Senior Challenge)
This is the flagship round of the competition, held annually in mid-November. Key details include:
Duration: 1 hour 30 minutes (90 minutes)
Total Marks: 80 marks
Format: Two sections — Section 1 contains approximately 15 short-answer questions (15 marks), and Section 2 contains around 5 longer, more challenging questions (65 marks), of which candidates are expected to attempt 3 out of 5.
Eligibility: Open to all students in full-time pre-university education (typically Year 13/S6 and below, including younger students who wish to challenge themselves)
Topics Covered: Mechanics, electricity and magnetism, waves, thermodynamics, optics, and modern physics
Certificates are awarded based on performance: Distinction, Merit, and Certificate of Qualification. Approximately the top 30 performers are invited to proceed to Round 2.
3. BPhO Round 2 (The Invitational Round)
Held in early February of the following year, Round 2 is significantly more challenging and is comparable in difficulty to the International Physics Olympiad itself.
Duration: 2 hours (120 minutes)
Total Marks: Approximately 40–50 marks (varies by year)
Format: Typically 3–4 long, proof-style questions, of which candidates attempt 2–3
Entry: By invitation only (top performers from Round 1)
Results from Round 2 are used to select approximately 5–10 students for the UK IPhO training camp, usually held at the University of Oxford in the spring.
4. Training Camp and UK IPhO Team Selection
The top students from Round 2 are invited to an intensive training camp where they undergo further testing, problem-solving sessions, and mentoring from experienced physicists and former Olympiad participants. From this cohort, the final 5-member UK team (plus reserves) is selected to represent the country at the International Physics Olympiad.
Recent Highlights: UK Team at IPhO 2024
The 54th International Physics Olympiad (IPhO 2024) was held in Isfahan, Iran in July 2024. The UK team delivered a strong performance, securing a total of 5 medals:
Silver Medals: Ivan Iakovlev (Exeter School) and Yingxuan (Alex) Wang (St Paul's Girls' School)
Bronze Medals: Dmytro Lutsiuk (Oundle School), Ewan McMillan (St Paul's School), and Daniel Zhao (St Paul's School)
Special Prize: Ewan McMillan was awarded the Experimental Prize, recognizing the highest score in the experimental examination among all participants
The team was led by Dr. Ian Brooks (Head of Delegation) and Dr. Richard Pamm (Deputy Leader). These outstanding results demonstrate the continued strength of the UK's physics education pipeline and the effectiveness of the BPhO selection process.
Looking Ahead: IPhO 2025 and the 2025/2026 BPhO Cycle
The 55th International Physics Olympiad (IPhO 2025) is scheduled to take place in Tehran, Iran, from July 19–26, 2025. Students must have been born after June 30, 2005, and must not have commenced university studies before July 2025 to be eligible.

How to Prepare for the BPhO
Success in the BPhO requires more than just memorizing textbook formulas — it demands genuine physical intuition, mathematical fluency, and the ability to think creatively under pressure. Here are some proven strategies for preparation:
Master the Fundamentals
Ensure a thorough understanding of A-level (or equivalent) physics and mathematics. Key areas include Newtonian mechanics, electromagnetism, wave phenomena, thermal physics, and basic quantum and nuclear physics. A strong foundation in calculus and algebra is essential.
Work Through Past Papers
The BPhO website (bpho.org.uk) maintains a comprehensive archive of past Round 1 and Round 2 papers with detailed solutions. These are widely regarded as the single most valuable preparation resource. Start with older papers and progressively work through to more recent ones.
Study Beyond the Syllabus
Many BPhO questions draw on concepts that extend beyond the standard curriculum. Familiarize yourself with introductory university-level physics textbooks. Recommended resources include:
Problems in Elementary Physics by Irodov — a classic collection of challenging physics problems
The Feynman Lectures on Physics — for deep conceptual understanding
An Introduction to Mechanics by Kleppner and Kolenkow — for advanced mechanics
Introduction to Electrodynamics by Griffiths — for electromagnetism at a higher level
Practice Showing Your Working
In the BPhO, full working must be shown. Marks are awarded not just for the correct answer, but for clear logical steps, proper derivations, appropriate use of units, and correct significant figures. Practice writing solutions that are both rigorous and clearly presented.
Join Study Groups and Seek Mentoring
Many successful BPhO participants benefit from working with peers who share their passion for physics. Study groups, online forums, and mentoring from teachers with Olympiad experience can be invaluable.
Why the BPhO Matters
The BPhO is more than just a competition — it is a gateway to extraordinary opportunities. Participating in the BPhO helps students:
Strengthen university applications: A strong BPhO performance is highly valued by top universities, particularly for physics, engineering, and natural sciences courses.
