What is the DMC?

The DMC (De Mathematics Competitions) is a nonprofit organization, established in September 2020 and led by DeToasty3, that makes mock contests for the AMCs and MATHCOUNTS. Along with ALP, DMC created ADMC in 2021, an original contest with prizes and sponsors.

Our YouTube channel may be accessed here. The DMC Committee will mostly use this for posting video solutions to past DMC problems, but we are open to any other video suggestions, which may be sent to pog in a private message on Art of Problem Solving.

Competition Math Tutoring

In April 2025, DMC launched their competition math tutoring service and has been helping students prepare for the AMC, MATHCOUNTS, and other contests. If you are a parent who would like their child to receive tutoring for math contests, please reach out to DeToasty3 at taikiaiba@gmail.com. Pay rates will be negotiated during an initial meeting and will start after a free trial tutoring session.
