Study Guide for ESS 21 Final Spring 2020 Your primary source of information is the lecture slides, quizzes, and discussions with the readings used to provide additional background information and to help you review anything you do not understand. If a term or topic is in the reading but we did not mention it at all in the lectures then you do not need to know it for the exam. We will be using Respondus Lockdown Browser and Monitor to proctor the exam online – you will therefore need a working webcam. The exam will consist of a mixture of short answer and multiple choice questions within Canvas Quizzes. During the exam you can use as many paper notes as you like but you will not be allowed to use calculators, any other electronic devices, or to communicate with anyone else. Below is a list of the important topics we have covered so far – concentrate on understanding rather than memorizing. I will give you formulae and I will not ask you to write out definitions (although they may come up in multiple choice questions). Anything that is crossed out will not be included in the Final. APPROXIMATELY 50% QUESTIONS WILL BE ON LECTURES 19-27 AND 50% WILL BE ON LECTURES 1-18.
