Thank you Helen!
It suddenly started to work. However, I set up a Required Course grade – 80.000, thinking that this would be a %. However, it counts the number of correct answers instead… So, for 20 correct answers out of 25 - the student gets a grade of 20 instead of 80 (%). This is Ok, but it can be confusing for students.
Does it have to deal with Marks (max grade) on the Questions? I had set them up as 1 mark (max grade) per question. If I change it to 4 marks, so 25 question would make 100% - should that work? It is not going to mess my quiz settings, correct? Or is it possible to make the required grade in Completion Report in percent?
Thanks a lot again.
