Radley Wipes Out is the tenth episode of Beverly Hills Teens.
Radley is ready to win a big surfing contest. Unfortunately, he can't even enter until he passes a history exam. But, despite the best efforts of Larke and Shanelle, Radley's "history block" remains. However, a clever pre-party game is put into play, using historical dates. Radley, knowing it was a game and not a test, rocks and rolls to win the game...much to the chagrin of Bianca, who was doing everything she could to get Troy to win.
