I did everything that is required - 1 inch margin all around, Courier New, 12 pt, double space - and I only get 22 lines per page, when I'm supposed to get 25. What's going on?
Do you have widows/orphans and all of those other special features that decide where line breaks should be turned off?
Sometimes you gotta fudge a little with the margins.
In Word done in Courier, go to paragraph format. Under line spacing, chose "exactly," and set it at 25. Done
