SAT II Science help

<p>I am currently a junior in high school and interested in schools such as CMU MIT and BC.
I was reading and CMU and MIT require SAT II sunbject tests for math and science. I have planned to take the Mth II because I am very math oriented and believe I can score high 700s. However, what do you think about the science test. I havent had Physics since freshman year so would it be hard for me to simply buy barrons and self teach myself everything again or is that to much of a stretch. I am currently enrolled in biology but don't really enjoy it that much and I think a technology school would like physics better. So my question is which test would be the best to self study and re learn everything by this time next year. And which book would you prefer barrons pr kaplans etc
Thanks</p>
