Sparknotes for Physics?

<p>i took sparknotes physics test and i got 730 but i thought the questions were easier than Barron's (which i get around 680-700) , PR (700) and especially easier than CB ( 650, I took the test 1 month ago). Even now i think the CB is the hardest. I've heard that Barron's is usually harder than actual test, how are PR and Sparknotes compared to the real one?</p>

<p>i thought differently!!! i'm going to take CB this sat....and ur post does not sound promising.</p>
