Homework 5

I have posted homework 5 here.

It is not due this coming Sunday.

Instead is due on the Sunday of the following week, July 8th.

This is to allow you time this weekend to study for the mid-term.


The mid-term exam will be given on Monday, July 2nd.

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.

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.
