Workshop

I have a serious problem with assessments for some workshops that have already been submitted and student-assessed. I realise that this module is about to be replaced, but unfortunately I'm stuck right now, so any help would be greatly appreciated. My problem is, the student assessments in quite a few cases are way out of whack (this workshop involves qualitative assessment of English writing, mostly by second-language-learners, so it's a tough exercise for them). I need to adjust the scores. With the default teacher weighting of 1, the results are far from acceptable.

• "This option can be changed at any time during the assignment."

..which is why I didn't try to make the decision about teacher assessment weighting up-front. On the other hand, Laura Christensen's on-line guide says:

• "The Weight for Teacher Assessment can not be changed after work has been submitted."

Can anyone confirm which is correct? (my experience seems to suggest Laura's guide is, but it would be helpful to know for sure that this is the source of my problems). If it is correct, is there any way for me to override the scores short of completely scrubbing the assignment within moodle and manually allocating scores? (I'm happy to delve into the php and fiddle with it if anyone can give a pointer as to where/why this is happening)

Thanks for any help
