Each of the labs is due six days from the day it was discussed in class, at 11:59pm. For example, if a lab was discussed on Tue, it is due the following Mon 11:59pm. Each lab is worth 100 points. If your lab is not completed on time, the late penalty is 100 points, i.e. your lab may receive a 0.
Grace period is 48 hours from the due date. You can only use grace period option twice in the entire semester. When using grace period, please email me with the subject containing 480/592 and the words "grace period". There is no late penalty for labs completed within 48 hours of the due date if you use your grace period option.
