· When composing your answers, be thorough. The more complete your answer, the higher your score will be. Be sure to identify any assumptions you are making in developing your answers and describe how your answer would change if the assumptions were different. For multiple choice questions if you think there are two correct answers choose the best one and justify your answer with reference. Please do not reproduce or just rearrange the words in the question as an answer but try to give some deeper logical reason. Use the spell check and other methods of writing correct and good English. [It will help me too to improve my English]
· While composing your answers, especially for the conclusions or the facts please support your answers, carefully cite your sources. If citing books include page numbers. I expect you to first get the answers from the OER, session notes and then other sources. If you are citing lessons, cite as (Session n). The session lectures are not developed 100% by me, so please avoid citing me as the author. Remember, failure to cite sources constitutes an academic integrity violation.
· Use APA format (so far, I have not penalized. But I expect you to follow it for the final)
