I believe the Education Edition is one year behind the commercial version, so you would need to have 2011 loaded on your home computer to not get the dreaded "future version" when you opened the files on your school computer.
Forget that. Listen to Lenny, He actually knows what he is talking about!
student\Educational SW 2012-2013 is SW2012 commercial. the first year, here being 2012, is SW2012 commercial
so next year SW 2013-2014 is SW2013 commercial......so on and so on and..... until V6 comes out
