Getting into Princeton's physics graduate program is highly competitive, with an estimated acceptance rate around 10%. Successful applicants typically have strong academic records, with GPAs around 3.9 or higher, and often possess GRE physics scores above 900, with some estimates suggesting a median score close to 990. Research experience is crucial; candidates are encouraged to connect with faculty members whose research aligns with their interests, as having a professor willing to support an application can significantly enhance chances of admission. Many applicants come from prestigious institutions, although there are successful candidates from less renowned schools as well. There are also discussions regarding the potential for different applicant experiences based on minority status, although this remains speculative. Overall, the admissions process is described as more about fitting into a specific research group than simply applying to the university itself.
