Dd#1 did really poorly on the knowledge subtest on the SBV and had scores all over the place on the whole test in general (I believe 16th-99th percentile). The 16th was knowledge. From the way the tester described the knowledge test to me, it didn't sound like a test of knowledge at all but more a test of looking for the thing that didn't fit or was wrong with the picture.
Dd had some very eccentric ways of looking at what was wrong. I'll give a made up example so that I'm not potentially giving away test questions should the example the examiner gave me happen to be a real question. Dd, for example, would be looking at a picture of an upside down tree and in terms of what was wrong with the picture would answer something like 'it has maple leaves, but an aspen trunk and I don't believe that you can graft those two types of trees together.'
If what the tester told me was accurate, I don't even know why that test would be called knowledge.
