Structural variations (3) [optional]
Residual analysis
A very complete, but somewhat atypical exam, with a Webex tutorial
Note: About half of each exam covers basic material, and the other half consists of questions of a more challenging nature. I grade accordingly, with the "pass" line at around 50%, and the rest of the questions used to separate the high passes from the passes. (So don't panic if you aren't sure how to do a few of the problems.)
