So when I was in my senior year of high school, one of my biggest questions/concerns about coming to college was how I would have to format my papers. Having only used MLA format for my entire academic career (and feeling that I had gotten pretty good at it), I was worried that my professors were going to want me to use a format that was completely foreign to me.

Well, hopefully I don't jinx myself, but so far, so good!
Most of my teachers have, actually, been pretty lax about it. Most don't seem to care what format you use as long as it's professional and you're not plagiarizing.

I mean, every once in a while, a teacher requests a specific cover page, or asks for the endnotes done a certain way (actually, I did have to learn how to do endnotes, but that wasn't really that hard), but in these specific circumstances, they typically give explicit instructions.

So, future college students, I hope that takes one more stress out of the whole process for you :)
