In my class I assign weekly reports, and my students are required to do a minimum of 10 of these over the course of the semester. However, they can do an additional 5 for extra credit. Each report is worth 10 points, so students have the possibility of getting 150% in this category.
Is there a way to give full credit (100%) to students who do 10 reports, but extra credit (up to 150%) to students who do more than 10? Currently I have each report listed as a separate assignment in a group, but this will mean that students will need to turn in the maximum number of reports will get 100%.
