Steve, I know what you mean. Though our tutors don't seem to get grizzly so much as overwhelmed and uncertain about persevering. I have to do a lot of spin about our open source ethos and how all software is buggy &tc &tc &tc. Ah well... The latest quiz is working now and is doing all we want it to do. The procedures for cleaning the code are a bit convoluted, but I think the tutor in question is up to it.
