GENERAL INSTRUCTIONS:
A.Write the exam using correct, Standard English employing good grammar and spelling.
B.One word, one sentence, or otherwise very brief answers are not acceptable. Usually two to three paragraphs per question should suffice, so there is no need to write a “Master’s thesis,” but answer each question concisely and completely.
C.You may use any source in print or on the Internet. However, you must cite your sources, even your textbook. Plagiarizing or copying from any source without citing the source is not acceptable. It will earn you an “F.” Citations must enable me to look up what you are referring to. I need the name of the publication, the author, the publisher, and when it was published. If it is an Internet source, I need a complete URL along with the name of the title and the author. Do not simply say “just Google it” or “check on Amazon.”
D.Write in your own words except when it makes sense to use a technical term. Do not “parrot” back answers from the textbook. Putting answers in your own words shows that you know what you are talking about.
