Yes, it was a very TOUGH test. They practically killed the kids with question number 1- LOL :-)
I think that this test has gotten progresively more difficult over the past three years. When you look at questions from 2006, they are dooable, most of them anyway. 2007 is more difficult and this year topped it. This test required some real math knowledge, not just logical problem solving. Some questions do require knowledge of CALC.
I like it though:-)
