Two midterm examinations and a final exam which will be the equivalent of ywo hour examinations.


Based on the class average scaled to a 75% C.

Thus, after scaling:

In arriving at a scaling factor, if the class average for a given exam is less than 75.00%, the difference is taken between 75.00% and class average, and this is added to each student's score. If the class average for a given exam happens to be greater than 75.00%, the difference between the class average and 75.00% is NOT subtracted from each student's score. Thus, it is possible for every student to get an "A." It practice this has not happened. The class averages for any given exam are usually below 75.00%. The final grade is based on the same procedure, but using the average of the averages.

Exam format:

Multiple choice exams machine scored.

All exams must be taken. Makeup exams will be available only to those who have a valid (in the instructor's opinion) excuse for missing a regular exam. Except under most unusual circum- stances makeup exams must be taken within one week of any exam missed, at a time and place to be indicated by the instructor. Because of the size of the class, this will be strictly adhered to, and multiple makeups will not be given. Therefore, make every effort to take an exam at the time it is regularly scheduled, and take every precaution to avoid missing one.

Lecture material:

The following topics will be discussed in lecture. For a more detailed coverage, consult the text.

Some of these topics will be dealt with more briefly than others. In addition, several video tapes will be shown, and the lectures will be accompanied by projection slides when this is instructive.
