<p>I signed up to take the SAT II in chem and us history on saturday but I never prepped for history and I think it'd be really dumb for me to take it saturday. How do I go about changing it to where I'm just taking Chemistry? Do I just not take it on that day or do I need to change it on my admit slip. Clearly I do not want to score a 0 on the test.</p>
<p>Just show up, take the Chemistry and leave. There will be no record ever made that you even signed up for the USH test (but they'll still keep your money)</p>
