> I don't understand the curve part of the bell curve...
Basically, the teacher takes all the students and lines them up from best to worst. The teacher then says, the top 10% get A's, the bottom 10% get F's, and the middle get a B, C, or D with most students getting a C. The curve part comes because the scale is curved rather than linear... 10% get A, 20% get B, 40% get C, 20% get D, 10% get F (for example). You points don't get you the grade, but rather your points simply order you in relation to everybody else.
> And how does one go about riding this curve?
If you do really well at the start of the class when it is easy, you are in the top 10%, or the A range. Later, you can goof off (i.e. put your time into other classes), knowing that you will drop down into the C range, at worse. This is riding the curve. However, if the bottom students all drop, then you are no longer in the middle, and instead drop down to the lower 10% and get the F.
