How do you use these study guides? See How To Study for the Quizzes, which is some general advice that past students of mine have found useful.

Below are statistical summaries of the results of the in-class quizzes
and the final exams. Letter grade ranges are not divided into +/- grade
boundaries (although +/- grades *will* be computed and reckoned
as part of the final grading). In general, the top quarter of each
range is +, and the bottom quarter is -, but this can vary a little from
exam-to-exam.

Federal Law requires that all individual students records be kept confidential, and as such individual test scores are not available electronically or by phone. Please see the professor or the TA in-person to retrieve your quiz and score sheets and so learn your grade.

For those of you wondering what all of the numbers mean, how the divisions among scores was derived, and how your grade is actually computed, see these additional pages:
