due date and overdue penalty
Due Date and Overdue Penalty
  • Due date for the reports:

- 2 weeks after the experiment date.

- The date of submission is counted by the date on which the hard copies of your reports are handed in to and signed by Mr. Dale Claude.

AND

- Electronic copies of the reports must be sent to both Dale and Dr. Niu by email on the same day for verification.

- When submission on weekends, the date of submission of reports by email can be counted, however, the hardcopies of your reports must be handed in to Dale on the following Monday to avoid extra delay penalty.

- 7 “free” late hand-in days for the whole course

- Must indicate on your reports when use it to avoid late penalty.

slide11

Due Date and Overdue Penalty

  • Penalty
    • - 10% of the full marks of each report per week (1.4%/day, including weekends, and other statuary Holidays), will be deducted from the late reports.
    • - Submissions including lab notebooks will NOT be accepted after
    • Dec. 5, 2012.
