<p>For Math Level 2, what exactly is necessary knowledge about series and vectors? I'm taking it next week, and I don't have a clue!</p>
<p>Well, that’s a problem then. Series and sequences are prominent.</p>
<p>Did you go to the college board website and do the sample test? Should give you a good sense of what to cram/review.</p>
<p>oohh now I realize what I was missing. I thought it was talking about series in a precalc/calc level context, not just more simple algebra II level stuff. Thanks!</p>
<p>The precalc ones are pretty much the same as the Algebra 2 ones.</p>
