The USA Biology Olympiad (USABO) is the premiere US biology competition for high school students. After two rounds of challenging exams, 20 students are invited to a residential training program at Purdue University where they experience labs and lectures with advanced biological concepts and exacting lab skills. The top four students go on to represent the USA at the International Biology Olympiad (IBO) in Singapore July 8 to 15, 2012. Online registration is open.
