Cancel sending of ACT scores

<p>I chose for my scores to be sent to four colleges or so when I signed up for the ACT. I know that my admissions ticket said that I could cancel the sending of these scores up until the Thursday after the test. I have since lost the admissions ticket and have no idea how to cancel the sending of the scores, which i don't think were as good as I wanted, to the colleges I selected. Can someone please tell me how?</p>
