Exams for the U.S. National Chemistry Olympiad Competition will be administered in April 2012.
Approximately 1,000 students sit for the 3-part national exam. No more than two students from any given school can compete in the national competition. The 20 top-scoring students are chosen to attend a study camp where they will try to win a spot on the U.S. team.
The three-part, 4.5-hour exam consists of the following (may be administered in any order):
- Multiple Choice
- 60 multiple choice questions
- Covers broad chemistry topics
- Problem Solving
- 105 minutes
- 8 written questions
- Covers chemical theories and models
- Lab Practical
- 75 minutes
- 2 laboratory practicals
- Involves problem solving in the laboratory
ACS calculates the average number of correctly answered questions by topic area. Scores are ranked as follows:
- outstanding performance
- above average
- below average
Students will only receive the performance ranking on Part I (multiple choice) of the exam. ACS does not distribute individual scores.
