Difference between "Math Level 1C" and "Math Level 1", etc

<p>Hi, I'm trying to fill out the beginning parts of my CommonApp (I have the anxiety of many of CC students and feel the need to do some of it) and when putting in my SAT subject scores I'm given the option to choose between "Math Level 1C" and "Math Level 1" and the same thing with level 2. What's the deal with the addition of the C? Which should I put?</p>

<p>“MathIC” was the name of the math subjective test in the old, old days, when “C” referred to the use of calculators. Choose “math level 1” :)</p>
