You have 75 minutes to complete this exam. You will have access to Blackboard. No other site is allowed and you will receive a “0” on the exam if other sites are accessed during the exam. This is an open book, open note exam; however, time may run out if you try to look up everything in the text or notes. Anything copied from another source must be in quotations and cited (citations do not need to be formal, for example Collins text p. 148 or ASC 740-10-15-3 is sufficient) — there will be a 10 point penalty for each incidence of plagiarism.  Citing sources found in a Google search that are not materials from this class is unacceptable.  Be sure to be thorough in your responses but do not include unnecessary information.
