Should I take & retake SAT II's?

<p>I got a 680 on Math 2, and I'm planning on applying to a few top schools so 680 isn't gonna cut it. I didn't study at all, and I guess I should have.</p>

<p>Also, has anyone taken the Latin SAT? I did a few practice problems on collegeboard but I think it's a little too easy to be practice problems. How hard are the problems on the test?</p>
