How it runs
Stay on this page while the clock is running. Switching tabs or apps is recorded. Two of those and your problems are withdrawn. A screen that locks itself while you are writing does not count against you.

Proof round

Problems on screen, proofs on paper. When time is called you get ten minutes to photograph your work and upload it to the submission form.

Guts round

Nine sets of three, answers only. Your team shares one answer sheet and one proctor thread. Submitting a set is final.

A proctor is reachable from inside either round.
