There's this app called quizup where it has a bunch of categories that you can compete against other people with timed quizzes. Normally I don't give two shits about these kind of apps, but 1: there's a halo section, and its actually pretty hard. 2: the app is actually pretty well designed. I earned the title last month for top 10 in california. So basically I'm like better and smarter than all of you.
