Problem sets and quizzes
Almost every Thursday and Wednesday, there will be a quiz at the end of class,
taken from an associated problem set.
(However, there is no quiz in the first week of the course,
and the last quiz is on June 2 Thursday or June 3 Friday.)
Unless otherwise specified,
all problems
are from the 10th Edition of Algebra & Trigonometry
written by Sullivan and published by Prentice-Hall (Pearson).
(The two class sections will always get different quizzes.)
