with real orgo section being only asking fundamental/foundational questions a lot, going from 2012 to 2014 version won't really make a huge difference, IMO.
I used an old version, had plenty of practice and covered every area that it needed to, I aced the orgo section with 27.
don't sweat it. destroyer is an overkill anyway, so if you went through it 3 times and know it solidly, you are good
