21, but this quiz isn't so accurate. I answered with the answers I'd answer during the school year. I've only gotten drunk twice since school ended. So, for instance, on question 2 I answered 10 because during the school year when I'd drink (on the weekends) I'd drink over 10 drinks. Likewise, I've been injured physically (falling, etc) so I answered yes but I mean people fall when they're sober too.
