<p>Chicago doesn’t want to see how you have been scored on a scale from 1 to 12 by some employee of the CollegeBoard. They would much rather evaluate your work themselves so that they can see your writing style and your thought process and hope to gain some insight into your personality. Numbers between 1 and 12 don’t tell much about personality.</p>
<p>By the way, I doubt anyone has ever written a Nobel Prize paper in 30 minutes. Chicago would rather remove time restrictions (to a certain extent) to see your mind’s fullest capability than try to guess at your ability to work under time constraints.</p>
