Should I Retake Biology E?

<p>I got a 690 on Bio E. I plan on also taking US History and one of the math SAT IIs. I am aiming for Vandy ED. Should I retake Bio? If so, which book would you reccommend to prepare with?</p>

<p>Thanks :)</p>

<p>I used PR and Barrons to get a 770.</p>

<p>Would you guys say that Sparknotes AP bio would be good to prepare for SAT II Bio?</p>

<p>I used Cliffs AP Bio and I was fine. I missed easy stuff, label the heart and pulmonary stuff.
750 E</p>

<p>lllllllllll</p>

<p>what is that suppose to mean?</p>
