How many credits do you need to get into Stanford?

Stanford doesn't use a "credits" system for admission. They look at your high school GPA, course rigor (the difficulty of the classes you take), standardized test scores (though these are currently optional), extracurricular activities, essays, letters of recommendation, and demonstrated interest. There's no specific number of credits required. The focus is on the quality and comprehensiveness of your academic record and the overall strength of your application.
