Registration will close on Wednesday, December 1, 2021. Login information for both practice sessions and the actual competition will be the same and will be emailed one day before each practice session and the actual competition itself.
Practice sessions will be run on Saturday, November 27, 2021 from 1:30-3:30pm ET and on Wednesday, December 1, 2021 from 6-8pm ET. Both practice sessions will use the same problems so you only need participate in one, although you are welcome at both! You do not need to participate the entire time, but you should complete a few problems to make sure you understand how the system will work, and figure out any strange issues that may occur.
The actual competition will run on Saturday, December 4, 2021 from 1:30-5:30pm ET! The site will open for logging in one hour ahead of time.
