Is SparkNotes SAT II (Math II) prep accurate?

<p>Will SparkNotes prepare me for the SAT II Math level 2 subject test? I'm taking it this Saturday. I'm in pre-calc right now. Also, to those that have taken this test already, what would you suggest to review the most?</p>

<p>Thanks in advance.</p>

<p>I took 4 of their tests already. My scores are scattered.
The fourth one I just took a few hours ago - it won’t even give me a proper score! It didn’t load properly or something, so it says I have a 0 score but that most of my answers are right! Anyway, I pretty much know what I got because I counted the number of questions I missed and such.
Not sure exactly what to review - but Sparknotes should help with that.</p>

<p>I took the first 3 Sparknotes tests and my score was in the range of 600-680. I took the Math IIC practice test from the Official SAT Subject Test Study Guide from College Board and I got a 710. The sparknotes tests are harder, but only by a little bit.</p>
