Something else that may be helpful for those seeking problems with solutions:
Midterms and finals for the past 5 years I have taught the class are available off my personal web page (click on a previous year for 561). Doing these problems by yourself is one of the best ways to prepare for the final - although be aware that some of these problems are from take-home finals and so are hard.
I also have *solutions* typed up for all of these past exams. I don't want to put the solutions on the web or release them publicly. However, for UNM students, you can come by and look at a print out of the solutions in my office (ITV students, contact me for separate arrangements). Also, if you email me a partial solution or where you are stuck on a problem, I'll be happy to email you a hint or the partial or full solution depending on how far you've gotten.
Also, this class has midterms and finals with solutions included:
