<p>I signed up for Math II, Bio, and Chem. To cancel the chem and take only the Math II and the Bio do I have to contact the agency beforehand or just not take the chem test this Saturday? I don't care if I don't get the $9 back either, it's not a big deal. Any input is appreciated especially if you can find text on this please post it on here.</p>
<p>You can simply leave and not take the third test. I have personally done this so I know that it works without any issues. The only consequence is you don’t get a refund but that’s not that big of a deal.</p>
