Homework 4

I have posted homework 4 here.

It is due this coming Sunday at 11:59 PM.

Mid-term

The mid-term exam for this course will be held on Monday, July 2nd.

It will consist of 25 questions like those on the quizzes.

You will have the entire class period to work on the exam.

60% of the questions will come from the Ungraded Class Quizzes.

The last class before the exam, Thursday, June 28th, will be a review session.

You will only be responsible for the material in the Class Notes for that class on the exam.

The Mid-term is a closed book exam.
