6. Test
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.
