I finally started doing useful things. If you're in 15-110 like my AP-failing self, this simple Greasemonkey script converts the total grades to percentages so you don't have to pull out a calculator or something ancient.
Download here - Greasemonkey script, Firefox / Chrome compatible
In the meantime, I'm working on chiptune covers of a few songs; hopefully I'll have them up soon.
