<p>It was my 1st time taking sat 2 and i didn't know we had to copy down Test Center Number to cancel the test. I tried using collegeboard and going to the high school website to find the number but i can't find it. does anyone know where i can find the Test Center Number or happen to know what the test number is for Hayward High School, California???? -thanks in advance</p>
<p>Do you still have your admission ticket?
If not, maybe try calling the school.
If that doesn't work, call college board and explain the situation.</p>
<p>Looking at my registration booklet, in Hayward, California,
Hayward HS is 05-307</p>
<p>Senor, I'm looking at my admission ticket and it doesn't say the Test Center number. The admission tickets are still online anyway.</p>
<p>THANK YOU ALL SO MUCH!!!
heroes all of you.</p>
