SAT II Math IIC - How accurate is PR Practice Tests?

<p>Alright so im taking the SAT II level two math on jan. 28. I got awesome grades in precalc and getting over a 100 in calc right now (*** mate?). Anyway the real problem is i let information flow out of my head as soon as i take a test... thats why midterms and finals are so damn hard for me... Anyhow I got the PR book and when throught he practice tests. It seems like for a lot of the questions you can just plug the answers into the problem and test them out. Just wondering how accurate this is to the real test? What about problem difficulty? Most of the ones i got wrong were silly mistakes... and plus i didnt go through all of the book before taking it so i didnt have Law of Cosines and polar crap memorized....</p>

<p>ANYWAY... any input would be great - thanks a lot!</p>
