The Intersecting Geekeries Test

Hi! This is that test where you have to know two different kinds of trivia to solve each puzzle.  The test covers five areas: Abstract math, physical science and engineering, computer science, Star Trek, and Buffy the Vampire Slayer.  There are nine questions in each category, for a total of twenty five.

Yeah, just back out now.  Nobody will think any less of you, I promise.
