PROBLEM SOLVED
It was a bad link!

The link to the 2ndExam Review went to last year's 2006 review (You should have known! It said due 12:00 March 24 [not March 23]) The link is now good for this semester, Spring 2007. Sorry for the confusion! In this year's practice exam, there are no DINOSAUR questions. All the links to the lectures work. It'll be worth your while to try it.
I'll grade the (2006) practice exams the way we agreed in class.
