What scores should I send?

<p>Hi, so I am just sending off my scores on collegeboard, when I noticed that some schools have
"X university has indicated that it considers your highest section scores across all SAT test dates that you submit. Feel free to send any additional scores that you want to make available to X university."
When it says "feel free to send any additional scores" does that mean I can choose to not send some of my scores?
If yes, then in my case, I took the SAT 1 in May of 2013, and I got 680 on CR, 780 Math and 800 Writing.
I took it again in Nov 2013, and I got 800 CR, 780 Math, 780 Writing.</p>

<p>Should I just send them my November score so they just see one good mark, or should I send them both of my scores, for that extra 20 points? Will they know that I used score choice if I just send them my Nov. scores?</p>
