Two-stage chemistry olympiad run by ACS local sections.
Our take
Local exam, then the national exam for top scorers. Reaching the national exam is the line worth having.
“Helps an application” is our read on how much an admissions reader is likely to weigh it: Strong means getting in or placing is a real achievement, Solid means it shows real interest and effort, and Light usually means most students who apply and pay can attend. It’s our opinion, not a ranking from any college, and a light one can still be a great summer.
