I am a graduate student and I'm T.A. of a graduate course. The professor asked us to give some assignments to the students. I have done so and a homework assignment, which contains an optional part for gaining extra marks, I designed.
Moreover, I have set a policy for late assignment being as follows:
- One day: Losing 25%
- Two days: Losing 50%
- Three days: Losing 75%
- Further outlasting ones: 100%
My intention was turning in both mandatory and optional parts together in one single written document. However a couple of students turned in that mandatory part by its due date, and optional parts after the due date.
Now, I am in a dilemma whether should I penalize their assignment or not. Also how about that optional part? Should I award extra marks or not?
