Welcome to the Orange County Math Circle!

The 2020 New Year's Invitational has been canceled.

Due to the first confirmed case of the Novel Coronavirus in Orange County late on the day before the tournament (Jan. 25th), OCMC is taking precautions and canceling the tournament. OCMC wants to protect the health and safety of all participants and volunteers. No rescheduling of the event is being planned.
