Is there a method (perhaps a *hack* as I see the situation so far) to implement a Grading Guide with items (criterions) with NEGATIVE points?
The reason for negative points in a criterion is to implement a penalty (say when the task was submitted after a deadline). Then the total mark for a task with an associated Grading Guide would be just the plain summation of all the points associated to each criterion (with negative points decreasing the total).
I am getting quite desperate as it seems there is no simple way to implement such an obvious feature.
Thanks for any suggestions,
