The three exams only cover the material from the previous lecture set. The third exam is not comprehensive. All exam dates should be considered to be firmly established. Any changes will be announced at least one week in advance, although no changes are expected. Of course, you are responsible for all information presented in class as well as the assigned readings whether or not you attend class regularly or read the text.
Exams always start at the beginning of the class period.
Late arrivals do not necessarily have the opportunity to take the exam once the exam session has started. If I am unable to conduct class on the day of a scheduled exam, plan on having the exam during our NEXT class meeting. Periodically throughout the term, you may have the opportunity to earn additional class credit which will be added to your total exam points. One example of extra credit is the participation in experiments as a research subject. As these opportunities arise, you will be accordingly informed.
