<p>I think I have to cancel June's Reasoning Score since
my CR is gonna drop.
Well, I downloaded the cancelation form but I have to
write the registration number.
But I threw away the admission ticket that day :(
Does anybody know what I should do? Or where
I can find my Registration Number??</p>
<p>Did you get an email from CB with the subject “Your SAT Admission Ticket”? If you did, the registration number should near the beginning of the email.</p>
<p>You might also be able to find your reg. number if you log into collegeboard. Some of my friends got it from there before the test (I just printed out my email).</p>
