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.
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.
