COMS 3203: Discrete Mathematics
Recitations — Fall 2026
Recitations
Recitations are optional, but strongly (strongly!) recommended — attendance is worth up to 4% extra credit
on your final grade. All recitation sections meet on Fridays. Sign up for a recitation section using the
"Groups" functionality on Courseworks.
If you really really cannot make any of the remaining available recitation times (in the afternoon) on Courseworks, please fill out this form.
