Barron's SAT USH vs. Real SAT USH?

<p>I'm taking the US History SAT Subject Test next week and I've recently started doing the practice tests. I've been getting a lot wrong. Is there a really big difference between the difficulty of the real SAT IIs and the Barron's one?</p>

<p>I remember taking the Math II tests in the Barron books and scoring 500-600s and getting a 790 on the real thing...</p>

<p>The questions in the Barron’s USH are harder than the real test. I took it last year and scored ~60 points higher than the Barron’s practice test. I guess it prepares you better for the test. BTW, I’m taking Math II on Saturday, do you recommend Barron’s???</p>

<p>Do any of you have an opinion on Sparknote’s USH? My first practice test was a 730, but I’m not sure if it was much easier than the real thing?</p>

<p>I have the sparknotes chem subject test book and am wondering how they are as well…
if I am in both AP chem and APUSH I am assuming the subject tests will be easier than the rigor of the AP exams- am I right?</p>
