Quizzes will closely follow the assigned homework. Please keep up with the homework as much as possible.

Midterm exams will follow the assigned homework less closely than the quizzes, but it will still be generally based on the work done in class and assigned homework problems.
The bad hair day rule is in effect. This says that your lowest scoring exam cannot be lower than 70% of the average of your other two midterm exams. Let me give an example. Suppose your exam scores were 40, 70, and 90. Then the average of your top two exams is 80 = (70+90)/2. Your lowest exam score would then be bumped up to at least 70% of 80, or 56; thus your exam scores would, in effect, be 56, 70, and 90. (If, in this case, your lowest exam score was, say, 60 instead of 40, then the bad hair day rule would have no effect.)
Midterm one will cover all the material we've covered through Friday, September 10th. This means Chapter 6, plus Sections 9.1, 9.2, 9.3, and 9.6. There is a review sheet (with solutions).
The exam, with solutions, is now available. See the results table, below, for details on how the class scored.
Midterm one will cover all the material we've covered through Friday, October 8th, since the first exam. This means Section 9.4, Sections 10.1 through 10.5, and Sections 11.1 and 11.3 through 11.5. There is a review sheet, together with solutions, available. Please send me email if you find any typos or mistakes in these solutions.

Below is a table of results for the exams and quizzes. (This is meant to give you an idea of the results from the class as a whole. One way to view the spread of the scores is via the average (mean) and standard deviation. A second way is to look at the quartiles: the first quartile is the score that marks the first 25% of the class (so 25% are below this score and the remaining 75% are above it); the second quartile marks the next 25% (so 50% are above and 50% below this score – this is the median); and the third quartile marks the score that only the top 25% of the class achieved.)

The point of a quiz or an exam is to prove to the grader that you know how to solve the problems asked. Thus the final answer is not the most important part of the exam; rather it is the work or reasoning behind the answer. You should show your work or explain your thinking in order to receive full credit.
Please see the exam page or schedule for more information on the time and content of the quizzes and exams.
