SAT Subject Tests on Common App???

<p>Hey guys, so I'm filling out my common app & for the SAT Subject Tests it asks you which tests you are taking and when. The thing is, I'm taking my subject tests in December, but I don't know which specific subjects I'm taking yet...
What should I do? If I put that I'm taking certain tests-will I be able to change them later? Or am I doomed to take whatever subjects I put on my common app?</p>

<p>Reason I ask is because some of the schools I'm applying to don't require SAT 2's but I can't submit my application until I complete the common app & the only thing I'm missing is the SAT Subject Test questions :(</p>

<p>Nevermind, I figured out how to do it!</p>
