For those to whom this long snow prelude to Test #1 seems to be dragging on forever, I've offered up another practice test. It's really the same test, i.e. just the numerical values in the questions changed. But in any case it gives you something to do other than just twiddle your thumbs. It's timed (75 minutes), 3-submission limit, and password protected (Password = "sampletest"). Feel free to ignore it. Your score on the sample test doesn't count anything toward your grade in the class.
IMPORTANT: Keep moving on your homework. If you wait until next Tuesday to get deeply into Part 3, you're going to fall behind in the class.
