How will competitive schools look at my subject scores?

<p>Hi guys,
I just took a couple of SAT subject tests over my high school years. I got 760 in chemistry, 710/730 in biology( I retook it, how will they look at this?), 680 in Math I( which i did not prepare at all) and 780 in Math II.
I was wondering since most college require 2 SAT scores, will they look at the two highest ( the chemistry and the math II) or will they consider that I did poorly on the others?
BTW the schools I'm aiming for are Columbia engineering, Cooper Union, Carnegie Mellon, Stanford and UC Berkley</p>

<p>Thanks in advance!</p>
