Ed,

>it's not capable of differentiating between the minimally clued and the true adept.

it's ? The concept or this particular implementation ? I think the concept is capable of this. Why should there be such difference between a test in a class about 100 miles away and a test on your own internet connection. Sure there are differences, but sure there are solutions which will be able to minimize this.

FYI, I don't draw conclusions on any particular test, unlike you want to tell the world I do. Just telling I like the concept.

Walter,
