Project Groups 16 Projects 3 -6 will be completed in groups of two � Unless we have odd numbers… � Yes, you can work by yourself, i. e. a group of one Partner selection � Pick whoever you want � You may switch partners between projects Yes, you can a different partner for EVERY project � Do not complain to me about your lazy partner Hey, you picked them Can’t find a partner? � Post a message on Piazza!
Late Policy 17 Each student is given 10 (!) slip days that they can use at any time to extend a project deadline � 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 � We normally give only 4; we are giving 10 to address stresses from this semester Assignments are due at 11: 59 pm, no exceptions � 1 second late = 1 hour late = 1 day late � After slip days are used, it’s 20% off per day late

Grade Changes 20 Each student is given 2 challenges to use as they see fit � Challenges can be spent asking for regrades If you think there has been a grading error, come to my office hours � If the grade is incorrect, you keep your challenge � If the grade is correct, you lose your challenge When your challenges are exhausted, you cannot ask for regrades Detailed instructions for challenges in on the class website
Grade Changes (Continued) 21 Challenges may be used for: � Projects, homeworks Challenges may not be used for: � Late assignments, use of slip days If you want to challenge a project grade, all group members must have an available challenge � Your challenge succeeds or fails as a group
