Hi HK,
If I understand your question correctly, you want to set the weight for a

ways to do that. I don't know if there is a way to set the default point value

Hi Itay,
What I normally say, and plan to say at a LON-CAPA workshop this April at the

absolutely true, but leaves the door open for someone to

Hi Itay,
I have never done this, but have noticed this semester that, when I create

Grade parameter to show up for one of my quiz

Is a cut and paste from MS Word OK for putting the Greek characters into the

Hi,
I am working on a problem for an upcoming exam. In the past I have just done it
via paper exam, which was fine until now. (I did plan to do it in LON-CAPA

The problem starts with an optionresponse. After the student answers it, I want
t ignore those parts of the array if they do contain
useful information.
They will be saved as part of the “submission” record for the student, but that
shouldn’t be a problem.
