How to create a grading key with bonus points only for 100% finished exercises

[martinmo]

Hi,

is it possible, in a course with programming exercises, to configure a grading key to calculate bonus points with the following constraints:

• each exercise with 100% score (and only 100%) gets 1 bonus point and
• at most 10 bonus points can be attained for the course.

I have tried several combinations with the editor at /course-management/<COURSE_ID>/grading-system/interval, but all had some issues:

• In the grading key editor, individual percentage scores do not seem to play a role; so I tried a key based on the overall percentage. We have 14 exercises in the course and the grading key that got closest to what I wanted involved having percentage intervals of ~7.14% (1/14, see screenshot below), but this doesn't seem to be precise enough.
• I also tried creating a key based on the overall points; but I probably misunderstood how it is supposed to work – mapping 1 point to 1 bonus point, 2 points to 2 bonus points, etc., with 1 point intervals up to to the max of 10 points didn't work and the maximum bonus point score students could receive was 7 bonus points, even if they solved 14 of 14 exercises.
• Just assigning 1 point to each exercise and using the sum doesn't work, because Artemis will sometimes round to the full point score even if the 100% score isn't achieved.

Thanks in advance & regards
Martin

PS. I am on the latest Artemis 6.3.8.

After reading through the Angular component sources and how the calculation works, I noticed that one can set a precision (number of decimal places) for the score and points calculation in the course settings. I've set it to 2 and that solves my immediate problem (e.g., 97% completion of an exercise results in 0.97 points instead of 1.0 points with one decimal place). Together with the overall points that is included in the excel sheet from the course scores page I have everything I need.
