I'm quite familiar with 12pt TNR
... it's been the norm for essays for quite a while.
I used to hate double spacing because I didn't understand that there was a layout function for line spacing that could double space for you instead of having to hit enter for everything line of text.
Good that you had so much content then! Sometimes that can be the hard part of an essay and you kick yourself later because you realize you could've substituted some fluff with some really solid evidence (.. or is that just me?)
