Places are based on a written test given in March. There are two divisions: the Regular Division exam is open to students who are in their first year of high school chemistry (other than an AP course); the Advanced Division to those taking their second high school chemistry course or AP chemistry. Each exam has a multiple-choice section and then a “tie breaking” section that consists of short-answer and essay questions.
The 2013 winners are listed below. This year’s Advanced Division top finisher is a repeat winner. Runpeng Liu also won in 2012 and went on to qualify for the International Chemistry Olympiad for USA qualifiers held in Colorado Springs last summer.
Update: Runpeng Liu qualified again for the Colorado Springs Training Camp, earned a spot on Team USA, and took a Gold Medal at the 45th International Chemistry Olympiad in Moscow. Way to go!
