I took the University of Florida test. It can be found on scioly.org/tests. I wouldn't say it is very hard. I thought it was hard because I didn't even study parts of the scales/intervals. I took it as a practice (a month away, so binder isn't 100% finished).
Well, I live in the Bay Area and there are 35 teams competing, so the tests will be harder.
Well. UF did release their detailed score breakdown available on their website. The highest score was 84.92. Assuming 1st place has the best PS and VS, and brought a log, they got a 66%. I think I'm not sure I did that math right. Another factor to consider is that this regional isn't particularly competitive. If a more competitive team was there, the high score would probably be much higher.
