<p>If I already signed up for the SAT but have not taken it yet, can I cancel the registration? If I do, will it show up on my score report as a score of 600 (min.)?</p>
<p>No, it won't show up as 600. If you cancel, there won't be any scores at all because you didn't take the exam.
Even if you didn't cancel, and just didn't show up to take the exam, there would be no scores to report.</p>
