retake this SAT II?

<p>i took 2 SAT's in May of 2006. </p>

<p>US History-680
Biology M-720</p>

<p>i'm planning on entering college as a biology/animal science major depending on where i go.
i just attended cornell's summer college program for 3 weeks and got multiple recommendations from people that i SHOULD NOT retake my SAT II's even for the Ivy's, because apparently anything high 600's and 700+ is good.
i was very happy w/ my scores, considering i started REALLY studying for them about a week before i took them, but my mom wants me to retake and get 750+ on Biology. will this be a waste of money and time?
i'm also going to take Math IIC and World History in November.
thanks!</p>

Sounds like you have your mind made up.</p>

<p>"Sounds like you have your mind made up."
well other people have been telling me it would be a waste of money/time. i'm not sure as of now.</p>

<p>If you think you can score significantly better,then you should definetly retake it(esp Bio since you are majoring in biology/animal science)</p>
