Are the Additional Essay's "Possible Topics" Exclusive?

<p>I've written an essay for another school that I would love to use as my additional Harvard essay. I would also love to move on to the other 24 essays I have to write by Monday (counselor-imposed deadline for RD). Does my essay have to be one from Harvard's list of "possible topics," or do they mean "possible" as in a list of suggestions?</p>

<p>Those are just suggestions. You are not limited to them</p>
