The current 
Problem of the Week.
You get up to 2 class points per week extra credit for our course 
from points earned in the problem of the week.  Problems
are graded on a scale of 1 to 4.  I'll give you
half that as extra credit class points (0.5 to 2 points).
FAMUS
(Friday Afternoon Undergraduate Math Seminar):  Fridays at 3 pm in AMB 164
Here is a flyer for MAT 239 or MAT 316 in Portugal this summer. The classes are filled and registration is closed. Maybe you can do this in Summer 2026.
Here is a discord chat about Differential Equations hosted by Jenna Sterry, who is one of our PMAs.
