Week 8: Final Exam
Instructions
The final exam is an five (5) question essay exam. This exam is cumulative and includes questions from material throughout the course. It is due the last day of class. 
Please answer each question in a complete and comprehensive essay with a minimum of 400-500 words. Your work will be run through TurnItIn. It is expected that you use your own ideas and proper citations. Quoted material should be minimal or not used. An essay is usually defined as a short piece of writing. Therefore, an essay is written in paragraph form with attention to grammar and spelling.  It should be concise and should directly address the question(s). Do not include information that is off-topic. 
You should refer to your lesson and in-class readings and resources to answer the questions. Outside sources may be used but you will be graded on the credibility and academic nature of the sources. You are required to cite any sources that you use. Proper in-text citations should be used and a references section at the end of each question. 
Each question is worth 10 points. If spelling, grammar, and proper references are not at graduate level, points will be deducted. Plagiarized or extended quoted material will not count as your work and no points will be awarded. 
Please use separate pages for each question response. Copy and paste the question before answering it so it is clear what question you are addressing. You may submit as a Word doc or a PDF. You must have a TurnItIn score for the exam to be graded.
