<p>Yeah, single space. You can separate paragraphs with extra newlines if you want, but double spacing (or 1.5 spacing) an essay of this sort is unorthodox and probably not the best choice stylistically.</p>
<p>Ok thanks, follow up question: is it okay if I don't use indentations? I generally just don't like to indent my essays, as I think it makes it look nicer. Anyone comment?</p>
<p>Wait, are you talking about the space provided in the Writing Samples portion or an uploaded document? I chose to upload my document and felt that double spacing looked much better.</p>
<p>I don't know anything about this stuff, but I 1.5 spaced mine. It didn't make it as long as double spaced would have, but I wanted to make it easier to read.</p>
<p>these decisions are really up to you guys. if you're not going to indent, just make sure there is a blank line between paragraphs. it will look like a big mess if there isn't.</p>
