Homework 6

I have posted homework 6 here.

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

Mid-term

The mid-term exam will be given on Tuesday, October 24th.

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, October 19th, 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.

Quiz 2

I have posted the answers to Quiz 2 here.
