Retake SATII?

<p>I took the SAT FAll of my junior year and got a 2170. I took the Math SAT II June of my junior year and got a 730. I am ok with my SAT score but think my SAT II score is low.
I did get a 4 on my AP Calulus AB. Should I retake any. If so which, and how much do i need to improve to make it worth it?</p>
