INSTRUCTOR: Hans Koch
  Office hours Mon Wed 1:30 pm - 3 pm, in PMA 12.152

WEB PAGES: Course information is posted at https://web.ma.utexas.edu/users/koch/M328K/.
  Access to some document files (lecture notes, exams, homework) is restricted.

  Attending classes is mandatory.
  Notes will be posted HERE one week in advance.

HOMEWORK: will be assigned/posted every Thursday HERE
  and is due the following Thursday in class.

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%)

  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.)
