General Guidance:

The exam questions below cover the material we will discuss in class. Your answers should reflect what we cover in class, the posted notes, and the text book.
It is best to work on the questions as we cover the material; you should feel free to bring the questions up in class for discussion.
Be thorough, it may take one or two paragraphs to completely answer the question.
Put the answer into your own words. Short quotes are OK, but your answer should not be a single, long quote from a source.
Please answer the questions using complete sentences, and be sure to use proper spelling and grammar (worth 10%).
The answers must be typed.
Informal citations are required.
- If you are using information from the textbook; indicate the page number
- If you are using information from your class notes; indicate so
- If you are using other sources, you should indicate the source
- Format examples: "According to [source], [followed by the information]" OR "[information] [followed by source in parentheses]"
Answers that are copied from the book, notes, another student, or any other source (verbatim or superficially rephrased) will not be accepted. While you should use all the resources available and you can and should work with other students, the work you submit must be your own work in your own words.
