In-Class Quizzes, Study Guides & Results
This page provides a schedule of the in-class
quizzes, summaries of the quiz results, and study guides.
There will be four in-class quizzes in addition to the Final Exam. The
schedule of quizzes is below. See the Course Syllabus for a description of
the quizzes and the course grading and makeup policy.
- In-Class Quiz 1: Friday, January 20
- In-Class Quiz 2: Friday, February 3
- In-Class Quiz 3: Friday, February 17
- In-Class Quiz 4: Friday, March 3
- Final Exam: Wednesday, March 15 9:30-11:18am
All in-class quizzes are held at the normal class time, 9:30-10:18am in
Evans 1008. You will have the entire class time to take the quizzes.
The Final Exam is in the same classroom from 9:30-11:18am on Wednesday,
March 15.
The study guides list the topics that will be covered by each of the
four in-class quizzes and the last weeks of class following Quiz 4.
Taken together they constitute the study guide for the Final Exam,
so no separate final exam study guide needs to be provided.
- Quiz 1 Study Guide
- Quiz 2 Study Guide
- Quiz 3 Study Guide
- Quiz 4 Study Guide
- End-of-Quarter Study Guide
The links above will become accessible during the week before each
scheduled in-class quiz.
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:

The Family
Educational Rights and Privacy Act of 1974 (FERPA) prohibits me from
posting any individual's results to the web. Instead, you will need to
pick up your quiz results in-person after class during the week
following them quiz. Graded tests will be brought to class every day
for the week after, starting on Tuesday, and then will only be available
by request during office hours, or during the following in-class quiz.
