Senior Jie Han works on a Rubik's Cube as Agora Days gets under way on Tuesday, Feb. 19. Agora Days is a Uni tradition in which regular classes shut down for four days. In their place, students choose from more than 100 mini-courses. The twist is that most of the courses are proposed, planned, and taught by Uni students themselves. Rubik's Cube 101 & 102, taught by freshmen Youyang Gu and Kevin Li, is one of the classes offered this week. In all, Uni students, faculty, parents, alums, and friends of the school are teaching 113 courses this year. The classes range from academic (47) to fine arts (12) to cooking (six) to games (13) to movies (16) to sports (11) to "other" (eight). Uni's regular schedule will resume on Monday, Feb. 25. After that, only three weeks to go until spring break!
