# Problem sets and exams

Almost every other Thursday, starting on July 27, but on September 12 Tuesday the last time, there will be an exam during the last hour of the class period, closely based on an associated problem set. (There is also a final exam on September 19 Tuesday, but this page is not about that.) Unless otherwise specified, all problems in the problem sets are from the 4th Edition of Elementary & Intermediate Algebra written by Sullivan et al and published by Prentice-Hall (Pearson).
