SAT Biology necessary for me?

<p>I signed up for this coming test date, but I don't think I can squeeze out a good grade
I already have two SAT Subjects (French and Math 2), and am applying to UC's, USC, and some liberal arts with a major in Bio.</p>

<p>So does it matter if I take it or not being that my major is in bio? I took IB Bio SL in Junior year and am currently taking BIO HL in senior year, so I should be fine right?</p>

<p>Thanks</p>
