Late submission will have 25% taken off the grade immediately, and an additional 25% taken off for each additional day.  A day is 24 hours from the specific time the assignment is due (e.g., if something is due at 6am Monday, and it turned in at 6:01am Monday, it is 25% off;  if it’s turned in at 5:59am Tuesday, it’s 25% off but will be 50% off at 6:00am Tuesday).
