Sending a big Walker congratulations to Gabriel Higbee! Out of 112,644 students across the world who took the Advanced Placement Macroeconomics exam last year, Gabe was one of 62 students who earned a perfect score. To receive a perfect score on this exam, Gabe had to answer all of the multiple-choice questions correctly, and all graders gave full points on the free-response section. Each exam is graded by multiple readers. Way to go, Gabe!
