American Mathematics Contest 12 aDminiStration
American Mathematics Contest 10 The AMC 10A and AMC 12A date is TUESDAY, February 10, 2009, and the AMC 10B and AMC 12B date is WEDNESDAY, February 25, 2009. The contests are
given at the same time to all participating students in a convenient 75-minute interval, preferably in the morning. The contests should be proctored by a faculty/staff

To offer more opportunities for students to participate, the AMC is encouraging colleges and universities to offer the AMC 10B/12B on their campuses. Contact local
math departments to see if they will be offering the B-date contests in your area. In the fall we will post the names of participating institutions on our website as they
