Grading: Homeworks: 25%, Quizzes: 5%
Midterm 1: 20%, Midterm 2: 20%, Final: 30%. Grading formula:
        HW = (HW1 + HW2 + HW3 + ...+ HWn) / n
        Q = (Q1 + ... + Qn) / n
        Overall = 0.25 * HW + 0.05 * Q + 0.2 * M1 + 0.2 * M2 + 0.3 * F
HW2, M2 etc are exactly the number you got, so if you got 112, that is what you put in.
Standard 90/80/70/60 scale will be used for final grades (curved if necessary).
All the exams are open book, open notes.

Note: the material covered in different exams depends due to different calendar positions of the exam and other factors. Furthermore, while the exams are representative of the style of the problems, you should not expect that the new exams are just variations with different data.
Integrity: All the quizzes, homeworks, and exams are individual work.
The division, college, and University are committed to honesty and integrity in all academic matters. We do not tolerate academic misconduct by students in any form, including cheating, plagiarism and commercial use of academic materials. Please consult the Golden Rule Handbook for the procedures which will be applied.
Verification of engagement: As of Fall 2014, all faculty members are required to document students' academic activity at the beginning of each course. In order to document that you began this course, please complete the following academic activity by the end of the first week of classes, or as soon as possible after adding the course, but no later than August 27. Failure to do so will result in a delay in the disbursement of your financial aid.
To satisfy this requirement, you must finish the first quiz posted online. Log in to Webcourses, choose COP 4600, and submit your answers online.
