Submission

All assignments are due in lecture (due dates are listed on the schedule)

Late Assignments

Late work will not be awarded any points. If foreseen or unforeseen circumstances prevent you from completing an assignment on time, you may request an extension. Extensions must be requested in advance of the due date.

Plagiarism

Presenting someone else’s ideas as your own, either verbatim or recast in your own words – is a serious academic offense with serious consequences. This will reflect in grades awarded as well.

Tests and Exam

Details will be updated soon.
