IT 116: Introduction to Scripting
Class 28

Today's Topics

Review

Final Exam

The final exam will be given on Thursday, May 17th from 11:30 - 2:30.

The exam will be given in the same room we use for this class.

It will consist of questions like those on the quizzes along with questions asking you to write short segments of Python code.

60% of the points on this exam will consist of questions from the Ungraded Class Quizzes.

Today's class will be a review session.

Even though classes do not end until the following week, today's class will be the last class.

Instead of having a Class 29, I will have Office Hours all day, from 11 AM to 6 PM.

You will only be responsible for the material in today's Class Notes and the review 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.
