Take whichever class is more interesting to you! Don't try to fit what colleges are looking for, because they're looking for kids that love what they're doing..
But....if you're interested in business, then stats is a class you'll be taking, and is much more related than environmental.
Also.....a lot of CSOM retake Statistics at BC, even if they've tested out of it with AP's, if they can get this one teacher who they say is pretty great. Of course, I'm sure there's multiple teachers, but maybe something to think about if you're serious about going to BC. Mcgowan - Boston College
