Math / Contest Math Class Descriptions

Online Classes: 2-hour weekly online classes via ZOOM. In addition, students are provided with reading assignment and handout with weekly homework problems to work on at beginning of week via Canvas.

Classroom Class (CM201-CM701): 2-hour class where 45-60 minutes of those are spent on lecturing. Rest of the time is reserved for problem solving.
