Why were my SAT Bio scores sent with my Nov SAT?

<p>So i just checked collegeboard and it said that my SAT Bio test was sent to colleges that i selected to send my SAT scores to. This is really bad because I did horribly on my SAT Bio test. Why were the scores for SAT Bio (which i took last year) sent on November 23, 2014, along with my November 8 SAT? And how can i prevent this from happening again, because I don’t want any more colleges seeing that score. </p>
