Sacramento Area Competitions in Mathematics


Welcome to SACMATH

(Last Updated: February 12, 2021)

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

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

SACMATH contests use tests from MathLeague.Org. MathLeague.Org is running online contests for the rest of 2020 and into 2021. For details on contest dates and how to register for contests, go to the MathLeague.Org website (

I expect results for AMC10 and AMC12 around the end of February or the beginning of March. Once I receive results, I will first notify any AIME qualifiers. Then I will send each student their score using the email address used when they signed up for AMC with me.

MathCounts is running all competitions online. They are offering four monthly practice competitions (October through January), two Chapter Competitions (February), and the State Competition (March). For more details on the contests and to register, go to the MathCounts website (

UC Davis Math Circle is holding virtual Math Circle sessions on Saturday afternoons. For more details contact Math Circle at [email protected].

ARML (American Regions Mathematics League) is happening in 2021, and it will be virtual! I will be organizing teams from the Sacramento Region to compete at the virtual ARML. Watch the website and the email list for details on date and practices.

SACMATH organized regional (virtual) sites for the AMC10 and AMC12 tests, for both A and B dates.

RESULTS: I expect results to arrive around the end of February or the beginning of March. Once I receive results, I will first notify any AIME qualifiers. Then I will email each student their score, using the email address given when the student signed up for the AMC test using my sign up form.

AIME is scheduled for Wednesday, March 10, 2021. I do not know if I am expected to be a proctor for AIME. If I am going to be a proctor, I will set up a ZOOM meeting and notify all qualifiers.

The 2021 Sacramento Valley MathCounts competition is occurring online. The Chapter Competition was Friday, February 5, 2021. The Chapter Invitational will be Thursday, February 25, 2021. 

ARML (American Regional Mathematics League) will be happening in 2021, and it will be virtual! ARML is one of the most prestigious high-school-level math competitions in the country. I will be organizing teams from the Sacramento Valley to compete at ARML. More details will be on the website (see the link above) and sent to the email list.
