Quiz 9

Let's review the answers to Quiz 9.


There will be no graded quiz next week.

Final Exam

The final exam will be given on Tuesday, December 19th from 3:00 - 6:00.

The exam will be given in McCormack 3-430.

There will be 50 questions, which will be similar to the questions on the mid-term and the quizzes.

As with the Mid-term, 60% of the questions will come from the ungraded Class Quizzes.

The questions will cover all of the material for this course.

The last class, Tuesday, December 12th, will be a review session.

You will only be responsible for the material contained in the Class Notes for that class, and the Class Notes for the review session for the Mid-term, which you will find here.

Although the time alloted for the exam is 3 hours, I would expect that most of you would not need that much time.

You will not be able to leave the room until you turn in your exam paper so you should visit the restroom before you take the test.

The final is a closed book exam.
