Use an HB pencil to fill out the scantron sheet. Ink and other pencils do not work – your answer will be invisible to the reader.

5.

An equation sheet is provided on the last page and may be removed from this booklet. All exam pages must be returned at the end of the exam.

6.

Closed-book exam: you may NOT have any notes or sheets with you during the examination other than the scantron sheet and the exam booklet provided.
