Homework 5

I have posted homework 5 here.

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


The mid-term exam will be given on Tuesday, March 20th.

This is the first Tuesday after the Spring break.

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, March 8th, 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.
