Please follow the instructions carefully.
You have 75 minutes (11:00am12:15pm) to complete the exam, and you should attempt all questions.
Be sure to fully explain your answers (except multiple choices).
Answers without work will receive no
credit.
Partial credit is given, so I encourage you to write down your steps in order to receive partial
credit.
Anyone found copying off of another student’s exam or consulting their textbook or notes during the
exam will be given an “F” for the course.
You may use a calculator on the exam, but you may not use a cell phone/pda/mp3 player as a calculator.
If you have two answers to a single question, you must crossout the answer you don’t want graded and
circle the answer you want graded.
If you fail to do this, you will receive a zero on the problem.
Good luck!
