Right now most of the material that's available is from my high school years, and from my freshman year at Stanford. Some of this is interesting or entertaining, largely because it's utter shlock (well, the college admissions essays are). The best from this period is the fiction from high school.
Most of the more recent essays are good but need rewriting. The Near Death research paper is probably the best of these.
The Old Stuff - from high school. Fiction, college apps, Shakepeare essays, and History essays.
Frosh essays: Essays written my freshman year for WCT (Writing and Critical Thinking) and CIV (Cultures, Ideas and Values).
Memic Evolution: evolution of ideas
A research paper on the "Near-Death" experience
