What extracurriculars are good for a physics major?
The strongest physics extracurriculars show that you engage with the subject experimentally as well as theoretically. A competition pathway from F=ma through USAPhO, hands-on research with a university professor, Science Olympiad build and measurement events, and eventually something you founded or built independently form a cohesive story. Depth in two or three of these areas is far stronger than broad participation.
Does USAPhO help with college admissions?
Significantly. The F=ma and USAPhO are widely recognized by admissions offices at top physics programs, and qualifying for the national exam round is a concrete benchmark that stands out in a large applicant pool. Camp invitation is an even stronger signal, but the first measurable step, a strong F=ma score, already distinguishes you from the majority of applicants who list AP Physics on their transcript.
Can I get into a top physics program without competitions?
Yes. Research experience is often valued as highly as competition results, and a student with a genuine university research project and a poster or publication has a compelling story even without an olympiad score. The key is showing that your engagement with physics goes beyond coursework: that you have measured something, built something, or taught something related to the subject.
