This is a list of some practice questions and problems for this week's
quiz. I encourage you to first, read the sections, and then try review
problems in the book. When that is complete, you should try these
problems and understand their solutions. This set of quiz questions is
not a complete list (and some of the questions are half-formed, so
there is no guarantee that any of these will appear on the
quizzes). 

This quiz covers chapter 12 sections.
