I'll fix it eventually.

You're going to college; so what high school math is really important, what will the colleges expect that you know? How do you prepare for the math placement tests you'll have to take? (If you don't pass the math placement tests, you'll have to take, and pay for, remedial math classes that don't count toward the requirements of your major.)

4/5/2008: I've just found a wonderful alternative to Geometer's Sketchpad; get it here: GeoGebra.org.
The two main advantages to GeoGebra are:
My first attempt is All Conics from One Directrix, which I could never get to work in Geometer's Sketchpad, but was easy in GeoGebra.
I intend to use GeoGebra exclusively from now on, and to convert my existing Geometer's Sketchpad constructions to GeoGebra as time permits.The Tangent Problem
