Barrons vs. Others?

<p>So, I have been taking some Barron’s SAT II practice tests and have been consistently scoring lower than when I took tests form another company (not remembering the name, rather unknown though). I got a 780 from the “easier” company and have been scoring 700’s average with Barron’s. What should I expect on test day (in two days incidentally)? I have heard rumors that Barron’s is generally more difficult: how accurate is it?</p>

<p>My other option is to delay the test until October… Opinions?</p>
