Required ACT and SAT scores for Princeton University?

Princeton University doesn't publish minimum ACT or SAT scores. They are a test-optional institution, meaning submitting scores is not required for admission. However, while not required, successful applicants generally have extremely high scores if they *do* submit them. Think scores well above the 99th percentile on both exams. There's no magic number, and admission is holistic, considering much more than just test scores.
