Workshops offer a unique opportunity to work problems as a team member team with the guidance of undergraduate and graduate TAs. What are the workshops? Part Part one is a quiz on Blackboard under Assignments/Workshops Part 1 . Part one must be completed before the workshop. Normally it is available on Wednesday at 5 pm the week week before the workshop and due at 5 AM on the Monday before the workshop.
