Policy announcement: the syllabus did not address the relative weights
of quizzes and exams. The policy is this: each problem proposed in a quiz/exam
will have the same weight in the final average.  Since quizzes will have 3-4
problems and exams 6-8, it follows that each exam will enter the course grade
with about twice as much weight as each quiz.

of 300 possible points in the course. That's 4%, and therefore the quiz is consistent with U policy for the last week
of classes.
