Grading: The grade for this one credit course will be based on four considerations:

[1] The exam on Tuesday 13 April 2004 (50% of grade)
[2] A 1-2 page paper due on Friday 2 April 2004 (36% of grade)
[3] The abovementioned preflight questions (10% of grade)
[4] Participation in in-class ConceptTests (4% of grade)

You can also get a PDF version of the syllabus

I also provide, to ease your mind, a sample exam that you can look at. This "exam" consists of about half the questions I used on last year's test. Whether you think that means I definitely won't use them again (or definitely will) is up to you.

As the course goes on, I will occasionally send out emails to clarify confusing issues, or delve into things in more depth for which there was not enough time in lecture. I'll keep a copy of those things here. If you did not get these emails, and think you should be getting future emails, please email me!
