SAT Physics - score?

<p>Hi guys!
I am gonna take the SAT subject physics on the first of october. ( I am kinda of excited).
I was just wondering which book I should take as reference for the test.
I have used the barrons and now I am using the princeton review plus sparknotes.
I did two tests on the barrons and I scored 700 and 740, today I tried one test on sparknotes and I got 670 ( I found it a little bit harder). </p>

<p>Is the real test harder than barrons ( and easier than sparknotes)? </p>

<p>ps: I still have to take the two tests on princeton review.</p>

<p>On the real test I want and I should score over 750..
It is just a matter of memorizing stuff. </p>

<p>Any advice ?</p>

<p>I only used PR somewhat and got a 710. My PR scores were a bit higher though. You should do the tests from the two editions of the Official Study guide for SAT Subject tests. Those are old released exams.</p>
