Help me learn your names
Say your name before each question

You don’t need to ask me, just turn-in stuff late All group members must have unused slip days
■ i.e. if one member has zero slip days left, the whole group is late Assignments are due at 11:59:59, no exceptions
1 second late = 1 hour late = 1 day late After slip days are used, it’s 20% off per day late
