Are there any questions before I begin?
The final exam will be held on Thursday, December 18th from 3 to 6 PM.
The exam will be given in this room.
If for some reason you are not able to take the Final at the time it will be offered, you MUST send an email to me before the exam so we can make alternative arrangements.
The final will consist of questions taken from the Weekly Graded Quizzes, along with questions asking you to write short segments of Python code.
There is a link to the answers to the graded quizzes on the class web page.
60% of the points on this exam will consist of questions from the Graded Quizzes.
You do not need to study a Graded Quiz question if the topic is not mentioned in either the Midterm or Final review.
The remaining 40% will come from 4 questions that ask you to write some code.
To study for the code questions you should know
A good way to study for the code questions is to review the Class Exercises, homework solutions and Class Notes.
The last class on Thursday, December 11th, will be a review session.
You will only be responsible for the material in that review session, which you will find here, and the review for the Midterm, 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.
The final is a closed book exam.
To prevent cheating, certain rules will be enforced during the exam.
At the end of each semester we offer you the opportunity to say what you think about this course.
What have I done right?
What have I done wrong?
What can I do better?
You are not asked for you name.
So the submissions are anonymous.
I will not see your responses until after I have submitted grades for this course.
We collect this feedback through Course Evaluations.
I will use what you say to make this course better.
To complete the course evaluation, use the following link .
Quiz 10 was the last graded quiz.
Don't forget the Linix InstallFest this coming Saturday, May 3rd, from 9 to 5 in the McCormack Conference Room M03-0721.
Let's review the answers to Quiz 10.
