EXAMS: There will be two 75-minute midterm exams in CBA 4.332
and a final exam (location announced in November). See also HERE.
The course grade is obtained via averaging from the
number grades on the three exams and the homework.
Midterm 1: Thu Sep 21, 11:00 am - 12:15 pm (weight 25%)
Midterm 2: Thu Oct 26, 11:00 am - 12:15 pm (weight 25%)
Final: Mon Dec 11, 8:00 am - 10:00 am (weight 35%)
Homework: (weight 15%)
No make-up exams are given,
except in cases of documented illness or emergencies.
For students with documented special needs, a time extension
can be arranged if requested at least 10 days before the exam.
GRADING: Credit will be given mainly for valid, relevant, and comprehensible
solution steps. Just answers receive little or no credit.
Each exam is graded on a scale from 0 to 60 points
and is "curved" to a number grade from 0 to 100
via an affine function (example: grade = 10 + 1.5 * points).
The "curve" will be made public after the exam is graded.
The correspondence between number grades and letter grades is
93 -100 A
89 - 92 A-
85 - 88 B+
81 - 84 B
77 - 80 B-
73 - 76 C+
69 - 72 C
65 - 68 C-
61 - 64 D+
57 - 60 D
53 - 56 D-
0 - 52 F
Graded exams are returned in class roughly a week after the exam.
(Recall that class attendance is mandatory.)
