Acаdemic Integrity Pоlicy fоr the Exаm: Yоu mаy access only your Excel software, word processing software (which may also be saved and uploaded as a PDF file if desired), calculator, and 1 page of PRINTED single-sided notes. You may also use the cheat sheet you used for Exam 1. The notes must be printed and NOT electronically accessed. No previously created files may be accessed except for the exam document. It is fine to have one blank piece of paper for scratch paper on hand. You may NOT use other online resources, including GBEC 625 CANVAS resources, during the exam. You must not access another student’s exam work. Cell phones and email may only be used to assemble the exam, and only if you hand-draw a graph and wish to upload it to your exam document. (In that case, you may take photos of your graphs and email them to yourself to cut and paste into your exam.) It is fine to use Word or Excel, or another app to electronically construct a graph. All other exam answers must be typed, including all math. NO handwritten math is allowed. NO handwritten sentences are allowed. You are not allowed to provide or receive exam work from another student, nor exchange the blank exam document before, during, or after your exam. During the exam, you are NOT allowed to communicate with anyone about the exam EXCEPT the instructor if she is available. Violations of this sharing and communication policy would result in zero points earned on the exam. Your analysis must be written in your own words, except definitions you have memorized or copied from your allowed reference notes for the exam. Plagiarism on an exam question would result in 0 points earned on that question.
