<p>So I took the Math SAT II back in June. I'm studying for the December 6th test, and I took a Barron's diagnostic test. Some problems I missed included:</p>
<p>3-D coordinates
Matrices
Polar Coordinates
Permutations
Ellipses
Sequences involving Sigma
Sequences</p>
<p>I am really under a time constraint with everything going on right now. How much of the above should I really worry about learning and mastering? I don't remember the math SAT II well enough to remember if any of the above were on the real test I took in June. </p>
<p>Thanks a lot!!</p>
