Should I retake the SAT IIs?

<p>I recently received my SAT II scores. I got a 700 in Biology E and a 720 in US history.</p>

<p>I also have a ACT score of 36 and a 4.9 GPA.
I'm taking the SAT I test June 7.
I would ultimately like to go to harvard or stanford.</p>

<p>Is it worth it for me to retake my SAT II's? I am planning to take the Math II test in October and am unsure if i should retake biology and US with it.</p>

<p>any opinions?</p>

<p>If you feel you can do better on Bio, go for it. History is fine you don't need to retake there. </p>

<p>BTW I got a 700 on Bio too and I'm retaking in November.</p>
