A perfect score of a 36 on the ACT does not come easy, but Cypress Ridge High School juniorÂ William WangÂ did just that when he took the test on Feb. 27, 2017. On average, less thanÂ one-tenth of 1 percentÂ of those who take the ACT earn this top score, ACT Chief Executive Officer Marten Roorda stated in a letter to Wang recognizing his achievement.
