Here’s a little trick that I found out from a bright college student. You can effectively make your papers longer by replacing all of the periods with a New Times Roman font and making them a size 14.
Of course, increasing the font size always works, but by doing this on the periods only it won’t be noticeable. You’ll save some time by not writing a few extra sentences, although I’d avoid doing this with commas and semicolons. They might tip off your professor, especially if the rest of your paper is bullshit.
