<p>Some technicalities about the essay:</p>
<ul>
<li>What file type should it have? I read somewhere that .pdf is preferred, can anyone confirm?</li>
<li>What font size should it have? I guess 12 should be ok?</li>
<li>Many people on here say they double space their essay. Is that recommended/required? </li>
<li>Can titles be underlined, bolded, etc. or will that mess up on the Common App?</li>
</ul>
<p>Thanks in advance.</p>
<p>I really doubt that it matters what file type - I’m pretty sure most universities realize that the majority of people will attach a Word file. Font size should be 12. And no, double spacing your essay is not required; you can do it if you want. You can bold your title and press print preview to see how it comes out. Other than that your title really shouldn’t be bolded or underlined in the first place. My common app essay doesn’t even have a title :D</p>
<p>Good luck!</p>
