Retake 2190 in October?

<p>I got this score on the March 2010 SAT (it was my first test). My breakdown was</p>

<p>CR-710
Math-770
W- 710 (75 MC, 8 essay)</p>

<p>I am definitely retaking it, because I was expecting a much higher writing score (I messed up the essay because I read the question wrong). But should I leave it for October?</p>

<p>Also, what are the chances that my score increases to 2300 in the nest 6 months if I study?</p>
