Problem sets and exams

Almost every Tuesday (before Labor Day) or Wednesday (after Labor Day), there will be an exam during the last hour of the class period, closely based on an associated problem set. (However, there is no exam in the first week of the course, and there is an additional final exam on Friday in the last week.) Unless otherwise specified, all problems are from the 10th Edition of Algebra & Trigonometry written by Sullivan and published by Prentice-Hall (Pearson).
