Late submission policyEach assignment is due at the beginning of class on the due date. All late submissions will be subject to the following policy.
You start the semester with a credit of 3 late days. For the purpose of counting late days, a "day" is 24 hours starting at 11am on the assignment's due date. Partial days are rounded up to the next full day. You are free to divide your late days among the take-home assignments (3 homeworks and 2 projects) any way you want: submit three assignments 1 day late, submit one assignment 3 days late, etc. After your 3 days are used up, no late submissions will be accepted and you will automatically receive 0 points for each late assignment.
You may submit late assignments to Vitaly Shmatikov or Oliver Jensen. When submitting a late assignment, please indicate how many late days you are using.
