<p>Here’s what Yale has to say about creative writing supplements:</p>
<p>Creative writers who submit work for possible review usually have very well developed talents. Some have been recognized at a regional or national level and many have successfully pursued writing opportunities beyond their English classes and school literary magazines. If you are thinking about submitting extra writing samples, you might consider sending a carefully chosen short piece rather than a long manuscript. Bear in mind that the required application essays are the most important “writing samples" in an admissions file.</p>

<p>If it’s your main EC, I would definitely send something, but bear in mind their desire for brevity.</p>
