<p>I took Calculus BC only, but I got two scores (calculus AB and calculus BC).
Why?</p>
<p>An AB subscore is the AP score you would have likely got if you took the AB exam. What they do is they take the exclusively AB material, grade it, and tell you that score. It doesn't count for scholar award purposes, but your college might award credits for it.</p>
<p>Thank you.
I did not take Calculus AB. What is the meaning of the subscore?</p>
<p>Dude he just told you</p>
<p>OK. I know.</p>
