I use moodle 2.0.3 (I’ve tried 2.1 first, but Cloze multianswer questions don't work). The last three days i'm reading forums trying hardly to find out a way to change a quiz "Grade type". The only menu where it's visible is in Courses->Grades. Doesn't mater in which category the quiz is moved, there's no way to change its grade type - it's always inactive and always stacked on "Value". I need a test where all attempts with score less then 60% to be equal to "2.00" (the lowest mark, i.e. "not passed"). After that I need marks 3.00 for 60%-63%, 3.25 for 63%-66% and s.o. I'v manage to do something like this, using Letters, instead of "Real" (where 2.00 is the lowest letter), but i'm not sure if this is the most appropriate way (and the "Grade type" of the quiz is still "value" with no option to change it). I created a new scale (2.00,3.00,3.25,3.50,3.75,4.00,4.25,4.50,4.75,5.00,5.25,5.50,5.75,6.00), but as far as I can't change the Grade type to "scale", I can't use it.
So I really need your help. Please, tell me what I'm missing... how could i change the Grade type of the quiz and what is the best way to create the marking scale i'v described.
Thank you in advance!
