<p>Which chapters of Barron's for Math IIC DON'T YOu need to know? Vectors?</p>
<p>Yeah, if you don't have the time, skip the vectors. I don't remember there being any questions about them on the test I took. At most, there's only been one question about vectors in my practice tests.</p>
<p>any other sections? :/</p>
<p>I'm pretty sure determinants - which Barron's covers in some depth - were not on the Math IIc test (this year), but they might be fair game... check collegeboard.com to see exactly what topics are covered.</p>
