Sacramento (and Seattle?) Area Competitions in Mathematics


Welcome to SACMATH

(Last Updated: December 14, 2021)

SACMATH - Sacramento (and Seattle?) Area Competitions in Mathematics - is an organization led by Jeff Soesbe that has been running mathematics contests in the Sacramento region since October 2009. 

NOTE: As of December 2021, I have moved to the Seattle area. So I look forward to being involved in math competitions in the Seattle area too!

Due to the ongoing Coronavirus pandemic, all contests are currently online.

SACMATH and UC Davis are hosting a virtual site for the AMC Competitions: AMC10A/12A, AMC10B/12B, and AMC8. See details below.

MathLeague.Org is running online contests for the start of the 2021-2022 school year. For details on contest dates and how to register for contests, go to the MathLeague.Org website (

Feel free to contact me (Jeff Soesbe of SACMATH) at [email protected] with any questions. 

I hope you enjoy the contests!

AMC10B and AMC12B are done. MAA has said they will release scores in mid-December. At that time, I will contact students who have qualified for AIME and contact all students with their score.
