All questions on the examinations are open to the Activity Guide, your graded homework, and other written material and notes that you generated during the course. You may also use an electronic calculator and at times you may be required to use one of the computers to collect data, perform analyses, and make calculations. The examination is not open to your textbook or other books, published exam or homework solutions, and other people's ideas. You may not work with or gain assistance from anyone except your instructor. To get full credit you must explain all your reasoning carefully, unless otherwise stated.
