Score selection?

<p>If I take an SAT 2, am I required to send it to any college I apply to if I don't cancel my score right after the test? I'm asking because I'm nervous that I don't have enough preparation for the USH SAT2. Ideally, if I get a bad score when I take it (next weekend), could I take the test the next date? If I get a better score then, can I send just that score? </p>
