Meetings Every Friday Lunch on Zoom!
Gunn Math Circle


Catch us during the virtual club fair on September 23rd!


  February 4, 2021 (A) & February 10, 2021 (B)

The AMC 10 is a 25-question, 75-minute, multiple choice examination in secondary school mathematics containing problems which can be understood and solved with algebra and geometry concepts. The AMC 12 is a 25-question, 75-minute, multiple choice examination in secondary school mathematics containing problems which can be understood and solved with pre-calculus concepts. Two different versions of the contests are given on two dates, about two weeks apart, in February. Each AMC 10 and AMC 12 contest contain about 12 of the same math problems.

The USA IMO (International Mathematics Olympiad) team selection series of contests begins with the AMCs (American Mathematics Competition), which all of Gunn is eligible to take. If you're an underclassman, you can elect to take the AMC 12 instead of the AMC 10. If you're an upperclassman, you can only take the AMC 12. All test versions have 25 multiple choice questions roughly arranged in ascending order of difficulty, given 75 minutes for 25 multiple choice questions with five answer choices each.

The American Invitational Mathematics Examination (AIME) is a 15 question, 3 hour examination in which each answer is an integer number from 0 to 999. The questions on the AIME are much more difficult and students are very unlikely to obtain the correct answer by guessing. As with the AMC 10 and AMC 12, all problems on the AIME can be solved by pre-calculus methods. The top AMC scorers are invited to take the AIME. This is a harder test where perfect scores are very rare.


The top AIME scorers are invited to take the United States of America Mathematical Olympiad (USAMO) and the United States of America Junior Mathematical Olympiad (USAJMO), which are six question, two day, 9 hour essay/proof examinations. All problems can be solved with pre-calculus methods. Approximately 270 of the top scoring AMC 12 participants (based on a weighted average of AMC 12 and AIME score) are invited to take the USAMO. Approximately 230 of the top scoring AMC 10 participants (based on a weighted average of AMC 10 and AIME score) are invited to take the USAJMO. The USAMO and USAJMO are given on two consecutive days in late April.


The Stanford Math Tournament (SMT) is an annual math competition for high school students held in the South Bay. There are multiple rounds: a team, power, and individual round which consists of either two topical tests (in Algebra, Geometry, Combinatorics, and Calculus) or a one general test.


The Berkeley Math Tournament (BMT) is a math tournament at Berkeley similar to SMT or HMMT. There are a number of rounds, including a team, power, individual, and tournament rounds.

  November 2020, February 2021

The Harvard-MIT Mathematics Tournament (HMMT) is an annual competition similar to SMT and BMT. Teams of eight compete in multiple rounds including a team, individual, and guts rounds.


The Caltech Harvey Mudd Math Competition is a team competition for high school students organized by the Caltech and Harvey Mudd math clubs, with help from Columbia University Competitions in Math.


The Carnegie Mellon Informatics and Mathematics Competition (CMIMC) is an annual math and computer science competition held at Carnegie Mellon University by CMU students.


The BAMO (Bay Area Mathematical Olympiad) is held the last Tuesday of February. There are no prerequisites to taking this Olympiad, which consists of 5 questions in 4 hours. The difficulty range is medium AIME to easy USAMO. In addition to winning many t-shirts, Gunn typically does well enough each year to win a $150 gift card to Chevy's, which we use for our annual club dinner (at Chevy’s).


The ARML Power round is a 60 minute team test with no cap on the maximum amount of participants where students work together on proof-based problems. Problems usually build up to an interesting idea in mathematics and are all based on a common topic. Questions range from medium AMC level to easy USAMO level.

  October to March

The CAML (California Math League) is a short exam consisting of 6 questions spanning over a lunch period. The CAML is typically held six times throughout the school year monthly on Tuesdays at lunch. This contest is the easiest it gets for competitive high school math competitions.

  All Year

USAMTS (USA Mathematical Talent Search) is a series of proof-based tests which can each be taken over a month without a time limit. You are allowed to use pretty much anything (Wikipedia, Wolfram|Alpha, an abacus, etc) except help from another person. Students who perform exceptionally are granted an alternative route into the AIME. Three month-long rounds allow for plently of time to work on problems.
