<li>Does Harvard have its own application separate from the common app?</li>
<li>Harvard's supplement essay is that very broad 5-option thing at the end of the common app, right (ex. unusual circumstance in your life)?</li>
<li>When it says "what language, other than English can you read, speak, or write" does that mean that language has to be fluent? Also does sign language count for this?</li>
</ol>

<li><p>No.</p></li>
<li><p>Harvard invites you to send in a supplemental essay, if you wish. They list five possible topics (not exclusive topics), including a general “unusual circumstances” one. They are not the Common App topics.</p></li>
<li><p>I believe that Harvard expects you to indicate if you are fluent in a language in speaking, reading or writing (but not necessarily all three). I see no reason why you could not indicate that you are less than fluent in a language, especially if that language would not otherwise show up on your HS transcript.</p></li>
</ol>
<p>With the exception of Question 3, I can see no reason why you could not figure this out on your own and felt it necessary to “bump” the topic.</p>
