The Approximate Number System aptitude test is something I’ve taken three times before: in 2012 (before I started my math degree), 2014 (right before I got my math degree), and 2016 (right before I got my MS in stats). So let’s take it again after several years of teaching math and stats and see if anything’s changed!

Eh, they’ve changed a little. My w was 0.13 all the other times I’ve taken this. Probably means I’m getting dumber. If that’s even possible.
