Help!!!! Chem SAT II

<p>So I'm planning to take the SAT II in math iic and chemistry this year. I originally signed up for chem on the May date, but it turns out I can't go.</p>

<p>I decided to move it to the June 2 date, when I'm taking the math. On collegeboard, it says to call and change the date, and that you have to pay $20 to change your test date. </p>

<p>The guy told me to just show up at the June date, go to registration and tell them I want to take the chem test in addition. And to bring 8 dollars with me. My admission ticket for the chem satII wasn't updated at all.</p>

<p>Is this what I'm really supposed to do? It just seems really different from what collegeboard said..and what happens when I just don't show up on May 5th for my chem SAT?</p>

<p>I'd really appreciate someone explaining this to me >__< thanks</p>
