2015 was marked by a series of unprecedented complaints directed towards Harvard. Specifically, the group SFFA – Students for Fair Admissions has filed a complaint in November 2014 regarding a bias in the Asian student admission procedure. They argued that Harvard has set up a system that holds Asian students to higher standards than the others, and forces them to compete.
