Physics Olympiad (IPhO) Past papers Questions
International Physics Olympiad (IPhO) is the Toughest Physics Competition for high School students, which held every year in the month of June – July in a different country. It is also known as the World championship Physics Competition.
The main aim of IPhO Contest is to test the highest level of knowledge in Physics, critical thinking, problem solving, right practices of presentation and analysis, and handson skills in theoretical and experimental physics.
Here, High school Students or Physics Olympiad candidates will get all the guidance, Notes and the Past papers of IPhO, that will help you to understand about the level of this test and to achieve High score in this contest.
