If I cancel scores, is there any way for colleges to know?

<p>I'm signed up for the SAT subject tests in bio and USH tomorrow, but I'm completely unprepared. If I go take them as a practice anyway can I just cancel the scores without colleges ever knowing? Including schools that don't take score choice, like Georgetown. Collegeboard won't let me change the date at this point, anyway, so I figure I might as well get some use out this testing date. I just don't want to have negative consequences for it, lol.</p>

<p>The colleges will never know, I have personally posed this question to Collegeboard and asked on cc. You have nothing to worry about, I did the same for a World History test.</p>
