The Hacker Test - Version 1.0

This test was conceived and written by Felix Lee, John Hayes and Angela Thomas at the end of the spring semester, 1989. It has gone through many revisions prior to this initial release, and will undoubtedly go through many more.

(Herewith a compendium of fact and folklore about computer hackerdom, cunningly disguised as a test.)

Scoring - Count 1 for each item that you have done, or each question that you can answer correctly.

If you score is between -> You are

Note: If you don't understand the scoring, stop here.
