Disks are due at the beginning of the class period on collection days.
Late disks will not be accepted without a valid excuse, and may be subject to severe penalty even with such an excuse. In the case of the Practice Exercises only , they may be retaken and resubmitted when the disks are next collected. If a score on a resubmitted set of Practice Exercises is higher than it had been earlier, the higher score will replace the original in the Grade Book. Grading is based entirely on the total number of points received. With the exception of the in-class final and points for regular attendance, points are obtained by taking Practice Exercises and Examinations in Logical Reasoning .
