We will cover approximately the following sections from the book: 1.1 1.6, 2.1 2.3, 2.6, 2.8 2.10, 2.13 2.15, 5.1 5.6, 5.8 5.9, 10.1 10.4, 10.8 10.10. Calculator: The use of a scienti c calculator will be assumed on all homework, quizes and exams. 1 A B C D F Raw (x) 95 92 86 83 82 78 75 73 72 (cut o at70) 66 64 61 58 55 50 48 47 40 Rescaled (y) 96 94 90 86 85 80 76 74 73 67 66 64 62 60 48 52 451 44 y= 100 90 (x 86) + 90 100 86 90 80 (x 78) + 80 86 78 80 70 (x 70) + 70 78 70 y= y= y= 70 60 (x 55) + 60 70 55 y= 60 x 55 Table 1: Grade rescaling Grading: The grading will be based on the following. 1. Written Homework Assignments and/or in-class quizzes. 2. 3 in-class (full period) exams. 3. The Final Exam (NOT Departmental). Exams will be announced well in advance. Quizzes will take only part of the class period and will be announced at least one class in advance. The in-class exams and the nal exam will all be equally weighted. I will drop the lowest of the four exams (hence, the grade on the nal could be drooped). The Homework assignments and quizzes will count for 15% of the nal grade, and the exams will count for 85%. For each exam or assignment, I (or the TA) will determine a grade range for the A s, B s, C s, D s and F s. I will then linearly resale the grades in the A range to the interval [90, 100], the grades in the B range will be rescaled to the interval [80, 89], and so forth. At the end of the course, I will simply average the grades and assign letter grades with cuto s 90% for A, 80% for B, 70% for C and 60% for D; I might lower these a little, but not much. Thus, with this system, you can determine your standing at any time. For example, consider a hypothetical exam with the raw scores as in Table 1. The grade ranges might hypothetically be chosen as indicated. The numerical 2 100 90 80 rescaled score 70 60 50 40 40 50 60 70 raw score 80 90 100 Figure 1: Graph of the grade rescaling function scores would then be rescaled as indicated in the table, using the formulas on the right and then rounding to the nearest point. The grade rescaling function would be as graphed in Figure 1. (The idea is that a score that was, say, halfway between the B and C cuto s should wind up halfway between 70 and 80. If you have any questions ask me. I m just getting the details on record here.) Final Exam: The nal exam is on Friday, December 12, 1:30 to 4:00 p.m., in our regular classroom. Class Attendance: I will not count attendance toward the grade. Remember that many studies show that skipping class leads to lower grades. Remember, you are responsible for all material covered in class and all announcements made in class. If you have to miss a class, you should check with me or a classmate to see what happened. Makeups: If you miss an exam you can, at your option, take that as the exam score to be dropped. If you are absent from an exam and have a legitimate excuse, I will give a makeup exam.
