# EXAM 3 REVIEW ## DISCLAIMER Hello everyone! Please keep in mind that this practice exam was entirely created by Kristin, a former SI leader. I do not have any knowledge as to what will truly be on your exam, so this practice exam is solely meant for you to practice what you know. This means that you may get tested on things that were not covered here, or you may not get tested on things that were. Furthermore, I am not an expert on the subject by any means as I am a student just like you, so I am prone to make mistakes as well. Always reference back to lecture notes and PowerPoints if you find a mistake on here. Best of luck :) ## Questions 1.
