How is GPA weighted at brown university?

Brown University doesn't use a weighted GPA in the traditional sense. They don't assign different point values to honors or AP/IB courses. They consider the rigor of your course selection when reviewing your application, but they don't mathematically adjust your GPA based on the difficulty of classes. Essentially, all courses are treated equally in calculating your GPA. The focus is on the overall strength of your academic record and the context of your high school curriculum.
