ACS Olympiad Exam at SIU

February 19, 2018

The U.S. National Chemistry Olympiad is a multi-tiered competition designed to stimulate and promote achievement in high school chemistry. It is sponsored by the American Chemical Society. Each year, four students are chosen to represent the USA in the International Chemistry Olympiad (IChO), which is hosted every year in July in one of the participating countries. The exam begins at the local high school level, which then progress to the national level, and then finally the international. Nearly 16,000 U.S. students participate in Local Chemistry Olympiad Competitions.

Test material is drawn from high school chemistry courses. You can see past course exams here.  The local exam consists of 60 multiple choice questions administered over 110 minutes. Students compete individually for the opportunity to take the U.S. National Chemistry Olympiad Exam. This year, the top 10 scoring students will have the opportunity to advance to the national exam.

The local section exam will take place on Saturday, March 24th in Neckers room 440. Students are asked to arrive at Neckers at 8:30am, in order to participate in laboratory tours and networking events with faculty and students before the exam is administered at 1pm.
