Withholding AP scores before applying to colleges?

<p>The College Board has an option of withholding your AP score. However, it says: "You may have one or more grades withheld from the report sent to the college you indicated on your answer sheet." So only seniors who've gotten accepted to college have this option? What about younger students who don't know which college they're going to yet (and thus didn't designate any college to send the scores to)?</p>

<p>Does anyone know?</p>
