New College Oxford Physics Interview

New College is one of Oxford's oldest and most distinguished institutions, founded in 1379, and its Physics interviews maintain a tradition of rigorous, problem-led assessment that has shaped the careers of physicists, engineers, and scientists across generations. Physics at Oxford is taught through a combination of lectures and tutorials, and the tutorial system demands students who can engage with unfamiliar problems, reason quantitatively in real time, and think conceptually about physical phenomena rather than simply applying memorised equations. The interview exists to identify whether you can do exactly that.

The Engineering and Science Admissions Test (ESAT) is your most important pre-interview tool. New College uses ESAT scores to shortlist candidates, and strong performance — demonstrating mathematical fluency, physical intuition, and the ability to apply principles to novel problems — is essential for securing an invitation. Crucially, the skills the ESAT tests are directly aligned with what New College Physics tutors probe at interview: candidates who prepare thoroughly for the ESAT arrive at interview with significantly stronger problem-solving foundations.

How New College Physics Interviews Work

Most Oxford Physics applicants have two interviews. New College interviews typically involve one or two tutors and last between 25 and 35 minutes. The format is almost entirely problem-based: you will be given problems to work through in real time, and tutors will watch closely as you do so, prompting when you stall and extending the problem when you make progress.

Problems in New College Physics interviews often span multiple areas of the A-level syllabus — mechanics, electromagnetism, thermodynamics, waves, and modern physics — and frequently require you to apply multiple principles simultaneously. A characteristic New College question might start with a straightforward mechanics problem and evolve into a question about energy conservation, then thermodynamics, as the tutor probes deeper. You should expect the difficulty to escalate as the interview progresses.

Mathematical fluency matters enormously. Physics interviews at Oxford require you to differentiate, integrate, and manipulate equations confidently and quickly. If you hesitate over basic calculus, tutors will notice. The mathematical skills you have developed in your Maths A-level are prerequisites for the Physics interview, not optional extras.

Preparation Strategies for New College Physics

Work through ESAT past papers systematically. Every question you find difficult is a signal about a gap in your problem-solving foundations. Do not just find the correct answer — understand why the approach works, how you could have spotted it more quickly, and what variations of the problem might look like. This analytical approach to past papers directly builds interview readiness.

Practise estimating. Fermi estimation questions — “How many piano tuners are there in London?” or “What is the total energy consumed by the UK in a year?” — are common in Oxford Physics interviews and require you to make reasonable assumptions, apply physical reasoning, and arrive at a plausible order-of-magnitude answer. The habit of thinking quantitatively about everyday physical phenomena is something that strong Physics candidates develop over months, not days.

Deepen your conceptual understanding of the areas where A-level tends to be most superficial: quantum mechanics, special relativity, and the physics of materials. Tutors frequently ask candidates to reason about these areas at a conceptual level, and candidates who have read around these topics — through accessible texts like Feynman’s Six Easy Pieces — consistently perform better than those who have stuck strictly to the A-level specification.

Frequently Asked Questions

How important is the ESAT for New College Physics?

The ESAT is central to the shortlisting process and New College uses ESAT scores as a primary filter before interview invitations are issued. A strong ESAT performance — typically in the upper quartile — significantly increases your chances of being invited. Equally importantly, ESAT preparation directly builds the mathematical and physical problem-solving skills that your interviewers will assess.

Do I need Further Mathematics for Oxford Physics?

Further Mathematics is not formally required, but it is strongly advantageous. Many Oxford Physics applicants do have Further Maths, and those who do arrive with stronger mathematical foundations for both the interview and the course itself. If you are not studying Further Maths, ensure your core Mathematics is fluent and that you are comfortable with calculus, complex numbers, and vectors.

Will I be asked to estimate things in the interview?

Estimation questions — Fermi problems — are common in Oxford Physics interviews. Tutors ask them to assess your physical intuition and your ability to reason quantitatively from first principles. The “correct” answer is an order-of-magnitude estimate, not an exact value. Practise estimation regularly: how much energy is in a AA battery, how long would it take to fill a swimming pool, what force does atmospheric pressure exert on your skin.

What should I do if I cannot remember a formula in the interview?

Derive it, or reason about what it should look like from dimensional analysis. Oxford Physics tutors are generally not interested in whether you can recall equations — they want to see whether you understand the physics well enough to reconstruct the relevant relationship from first principles. If you forget the equation for kinetic energy, think about what quantities it must depend on and use dimensional analysis to narrow it down. This kind of reasoning is exactly what the interview is designed to reveal.
