Math 2 or Math 2C

<p>In the Common App, under Tests-SAT Subject Tests-Subject, they have the options Math 2 or Math 2C. What is the difference? How do I find out which one I took? Is one of them an older version of the test? </p>

<p>Edit: I took the November 2009 test</p>

<p>then it’s just 2</p>

<p>2c was a few years back</p>

<p>Thanks 10char</p>
