It's Caribou Contest Day!

You can start the contest once anytime within your school's Contest Time Window. By default, the window is Wednesday and Thursday, 7:30AM-3:30PM in your school's local time zone. Your school's Caribou Coordinators may modify the window, but the last possible time to start the contest is 6:30PM EST (Eastern Standard Time). Questions about Time?

You will need your Access Code to sign in. You can use a pencil and paper for rough work, but no calculators.

Preliminary results are announced around 8pm Thursday EST and finalized within a week. Sign in to see your results.

Best of luck & have fun with math!
