Should I take March 2011 SAT?

<p>I took my first SAT in January but didn't do so well. It wasn't a bad score for a first time taker, but 150+ lower than my practice test average and PSAT. I would like to think that it was a test day anxiety, but what if it was not? Not sure how much I can improve my score by practicing over few more months. Should I take March one and see what my real score would be? or should I study more and take later? Anybody with similar experience?</p>
