Should I retake SAT/SAT II's/ACT for engineering?

<p>I plan on applying to Stanford and the top 6 UC's for Biomedical or Chemical Engineering. I currently have a 1980 SAT, 29 ACT, 700 Bio E and 620 Math II.</p>

<p>I'm already aware of the fact that I need to retake Math II for a 700+. Since Bio is 700 flat do I need to retake it, or would it be more beneficial to study for the Chemistry SAT II? Also should I retake the SAT/ACT or can I just leave it alone at this point? I'm already in range at the UC's with my SAT/ACT, but I know engineering has higher unpublished numbers, so I'm not sure what puts me in range for that.</p>

<p>I have a job, Community College classes and summer AP work, so I'd prefer to prep for only one test this summer.</p>

<p>Thank you all for your input!</p>
