Project

Part I of the project is due Tuesday, April 29, 11:59 pm PDT.
I'd advice not working Part I until after working assignment 5.
You can look at it immediately though.

Midterm Exam

You can work the Midterm Exam after viewing Session 17.
Your Midterm Exam must be emailed back to me no later than Monday, April 14 (earlier depending on when you receive it).
You will have 72 hours to work the exam from when I email it to you.
Send an email requesting a day and time (Pacific Time) that you want it emailed to you.
Please give me atleast 48 hours advance notice before the time you desire(?) the exam.
