As far as formatting the essays go, is it OK to Justify or should we stick to Align left. It reads much more cleanly with Justify. Is there a set of published guidelines with regards to Word documents and Essays?

You know, i think as long as it's legible, either Justify or Align Left is fine. Personally, I prefer Align Left but that's just me

For formatting, Kellogg requires their essays to be double spaced. Also reading various threads about Kellogg - seems that most people tend to keep font size between 10 and 12.
hope this helps!
