<p>I signed up for math 2c and bio for may SAT2 subject tests.</p>
<p>However, since i have another ap stat test very 2 days later, I'm planning to take only Bio, since I'm taking AP Bio and mastered pretty much everything.</p>
<p>But math, I'm not quiet ready yet.</p>
<p>One of my friends said that If I signed up for 2 tests and take only one, both tests results will be nullified. </p>
<p>But isn't it possible to sign up for math 2c and take chemistry? Then why I can't sign up for 2 tests and take only one?</p>
<p>I know, I regret that I signed up for two tests. But if I can take only one I think it would be better haha. Or simply I may take math experimentally, and take it again on oct.</p>
