This morning I mailed the previous tests to the Director of the PLuS program. I sent all of the previous exams that I have. They go back to April of 1997. I also sent him the syllabus of SE431 showing that there were no references to Zed. This is the class that was supposed to teach Zed. I don't think that it is good policy to have an exam question on the tests that I have taken and not have any way to gain validation. I have a similar problem to a problem that was on the first test I took. The question was on structured vs OO analysis. What I could find on structured analysis was in an out of date book I got off of Amazon used from a guy in Canada.
