Quiz #4 is up and going

I had a little hicup with blackboard last night, but that’s all fixed now.  Quiz #4 is available for students now and will remain open for the next 24 hours.  Please make every effort to take the quiz.  You have to contact me BEFORE the quiz closes at 1PM on 11 March if you cannot take the quiz in order to reschedule a make-up.

Quiz, quiz, quiz… and something funny

Don’t forget the quiz that opens on Wednesday at noon.  It’s the standard 5 question “pick the best answer” style quiz.  Remember to email, AIM, or facebook me as soon as you have technical difficulty with Blackboard.  I can do nothing for you if you wait until the next lab meeting to tell me you couldn’t take the quiz; I need to know as soon as possible about any trouble with Blackboard.

And now for something completely different: http://www.xkcd.com/705/
