What is the DMC?

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

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.
