Drop in Subsection Score

<p>My three approximate SAT Scores are as follows:</p>

<p>1st:: R:680 M:800 W:620
2nd: R:640 M:720 W:800
3rd: R:710 M:750 W:650</p>

<p>Although I received an 800 in Writing my final SAT score in writing dropped 150 points. Do you guys think colleges will see that negatively? And how does superscoring work? Do I have to send in all scores and let the colleges choose the scores or can I specifically choose each subsection score to hand in?</p>
