                     It was a bit harder than I intended (Question
                     1 was supposed to be the easiest ☹). I
                     don’t curve, but I will provide opportunities
                     for you to improve your overall grade.
                     Extra credit this week worth 5 points - you
                     may redo one question from the exam.
                     Model answers will be posted after spring
                     break.
