Midterm Exams: Final Exam: 1: Fri, 25 Jan 2: Wed, 20 Feb Mon, 18 Mar, 10:45 am-1:15 pm Grading: Quizzes (2) 40 points Online Homework 60 points Exam points Exam points Final Exam 200 points Total 500 points Make-up Exams: All requests for make-up exams must be accompanied by a signed letter (with appropriate letterhead) from a physician no later than one day after the scheduled exam and must include a phone number for verification. There are no make-up quizzes Dropping the Course: The no record drop period spans from Jan. 7 through Jan. 14. After Jan. 14 you must submit a letter to the instructor from a physician stating that you must drop the course for medical reasons. You will receive a W on your transcript for dropping the course after Jan. 14. Grading Scale: A: 90.0%-100% Page 1 of 6

Book Homework problems. Book Homework problems are optional but are suggested as a way to increase understanding of lecture material. You will not be graded on these problems. Online Homework. Online homework will be assigned through. 1. Go to 2a. If you already have a account, log in, click ""View Available Courses"", then skip to step 3. 2b. If you have Facebook account, you can use it to quickly create a SaplingLearning account. Click "create account" located under the username box, then click "Login with Facebook". The form will auto-fill with information from your Facebook account (you may need to log into Facebook in the popup window first). Choose a password and timezone, accept the site policy agreement, and click "Create my new account". You can then skip to step 3. 2c. Otherwise, click "register here" located under the username box. Supply the requested information and click "Create my new account". Check your (and spam filter) for a message from and click on the link provided in that Find your course in the list (listed by school, course, and instructor) and click the link. 4. Select your payment options and follow the remaining instructions. Once you have registered and enrolled, you can log in at any time to complete or review your homework assignments. During sign up - and throughout the term - if you have any technical problems or grading issues, send an to support@saplinglearning.com explaining the issue. The Sapling support team is almost always more able (and faster) to resolve issues than your instructor. A web site with tutorial aids from the textbook publisher is available at Page 2 of 6

3 Academic Dishonesty: The California Code of Regulations, section 41301, states that the following are grounds upon which student discipline can be based: cheating, plagiarism, or other forms of academic dishonesty that are intended to gain unfair academic advantage. If caught cheating, students will get an F grade and will be disciplined by the College of Natural and Social Sciences. Americans with Disabilities Act: Reasonable accommodations are any actions taken to permit a student to: (a) have equally effective communication; or (b) to have equal access to instruction, programs, services and activities sponsored by the University. Providing reasonable accommodation is mandatory when: (a) The student has a protected disability. (Medical documentation may be requested to verify the existence of a protected disability and the need for reasonable accommodation.) (b) The student requests a reasonable accommodation. (c) A reasonable accommodation is required due to a protected disability. (d) It is possible to provide that accommodation without undue hardship. Undue hardship is a fundamental alteration in a program or service or an undue financial or administrative burden. Under the law, in most instances, it will be difficult to justify an exception based on undue hardship. Any situation thought to be an undue hardship must be discussed with the Equity and Diversity Specialist at: (323) (Tel), (323) (TDD), or (323) (FAX). Page 3 of 6
