PhysicsBowl is a 40-question, multiple-choice exam split into two divisions (Division 1 for students in their first year of physics, Division 2 for more advanced students). It’s a good lower-pressure entry point into physics competitions compared to olympiad-style exams, since it’s multiple choice and school-team based.
Ask your physics teacher whether your school already registers a team — if not, teachers can register directly through the link above.
