<p>I am prepping for the SAT II Math II, and am using the Barron's book, but there is a lot of information in it, is it essential I know all of it, in the sense is everything in it liable to come up on the test. For example, things like foci of ellipses and eccentricity, is that really liable to come up on the test?</p>
<p>lol you’re rite … ellipses are kinda outta the sat world in barrons … BTW its always worthy to know something extra … so yeah learn it . Thats what I did</p>
