The second exam was Friday, October 31, during lecture. This exam is worth 10% of the total grade, and replaces the grade of the first exam if the new score is higher. As before, books, notes, and calculators were allowed.

Failure to take the exam was graded as a score of 0.

**175:** The midterm covered Chapter 7 of the textbook (and assumed knowledge of Calc I).

**275:** The midterm covered Chapter 12 of the textbook (and assumed knowledge of Calc I and II).
