The International Physics Olympiad (IPhO) is one of the most prestigious physics competitions in the world for high school students. It brings together top young physicists from across the globe to test their understanding, creativity, and problem-solving. Whether you want to compete or you’re just curious, this guide covers the history, structure, how to prepare, and what comes next.
What is the IPhO?
The IPhO is an annual competition that started in 1967 and now draws students from over 80 countries. It challenges them with tough theoretical and experimental problems that test not just knowledge but the ability to apply it.
Each country picks its team through national physics olympiads, where the top scorers earn a place at the international event. The competition has two parts:
- Theoretical exam: hard problems across mechanics, electromagnetism, thermodynamics, and quantum physics, designed to make you think and apply concepts in unfamiliar ways.
- Experimental exam: you run experiments, analyze the data, and draw conclusions. This tests your practical skills and how you handle real measurements.

Why compete in the IPhO?
The IPhO is about more than medals. It pushes your physics further than the standard curriculum and connects you with students from around the world. A few concrete reasons:
- Recognition: the IPhO is internationally known, and doing well can help with scholarships and university admissions.
- Depth: preparing for it means going well beyond standard high school physics.
- Network: you meet peers from across the globe who share your interest, and those connections can last.
- Problem-solving: it sharpens how you tackle hard, multi-step problems, which carries over to any field.
If you’re aiming at the IPhO partly to strengthen your college application, here’s a video from Rishab Jain on the extracurriculars that got him into Harvard, Stanford, and MIT.
How to prepare for the IPhO
Good preparation means mastering the theory, building experimental skills, and getting fast at problems. Here’s how to go about it.
1. Master the fundamentals
Before the advanced stuff, get a solid grip on the core: mechanics, electromagnetism, optics, thermodynamics, and modern physics. A few standard textbooks:
- Fundamentals of Physics by Halliday, Resnick, and Walker (link)
- University Physics by Young and Freedman (link)
- Problems in General Physics by I.E. Irodov (link) — the classic problem book for olympiad prep.
2. Solve past IPhO papers
Practicing past papers is one of the best things you can do. It gets you used to the format, the difficulty, and the kinds of questions asked, and working them under timed conditions builds the time management you’ll need on the day.
You can find past papers and solutions at:
- The IPhO archive (ipho-unofficial.org), which has every year’s problems and results.
- Physics olympiad prep websites and forums.
- Educational sites like Brilliant and Physics Stack Exchange.
IPhO Olimpicos has hundreds of IPhO problems and solutions from 1967 to 2001.
3. Compete in national and regional olympiads
Before the international stage, get experience in your national and regional physics olympiads. They run in a similar environment, help you gauge where you stand, and are usually how you qualify for the IPhO in the first place. Research your country’s selection process, since some have several rounds.

4. Use online courses and study groups
There’s no shortage of online help. Courses on Coursera, edX, and Khan Academy can shore up tough topics, and many are taught by university professors with assignments and forums. Study groups, online or in person, are just as useful: you trade ideas, work hard problems together, and see different ways to approach them.
One option is Rishab’s Skool community, a group of 5,600+ students focused on science and research.
5. Build your experimental skills
The experimental exam needs hands-on practice. Use your school lab (or a small setup at home) to run common physics experiments. Focus on the principles behind each one and on collecting and analyzing data accurately. A few tips:
- Cover a range of topics: mechanics, optics, and electricity.
- Practice designing your own experiment from a given problem statement.
- Learn to use statistical methods to analyze data, which the IPhO often requires.
6. Find a mentor
If you can, find someone who knows physics competitions: a teacher, a former IPhO participant, or a professor. A mentor can give you tailored feedback, help you fix weak spots, and keep you going through the grind.
7. Build a study schedule
Consistency matters most. Build a schedule that balances concepts, problem practice, and experimental work, and stick to it while leaving room for revision.
Taking it further
The IPhO is a real achievement, but it doesn’t have to be the end. If you want to keep challenging yourself across science, look at the International Research Olympiad (IRO).
Unlike the IPhO, which is all physics, the IRO is multidisciplinary, testing research ability across many fields of science. In 2024 it drew over 1,000 participants from 45+ countries. Competing in it lets you take the skills you built for physics and apply them to real research projects. You can find details and register at the IRO website.
The bottom line
The IPhO is a demanding competition, but with steady preparation and real interest in physics, you can do well in it and open up a lot of opportunities. And when you’re ready for the next challenge, the IRO is a natural place to go. Good luck.
