How much harder is Barrons than the actual US History SAT II test

<p>Ive been studying for the Sat II US history for the past week and I've been using Barrons to study. Ive been making low to mid 600s on the practice tests and this really freaks me out because I'm aiming for 730+ on the test. I took APUSH this year and did really well. So how much harder are Barrons practice tests in comparison to the actual exam?</p>

<p>Same question. The practice test questions on the CollegeBoard website are a joke compared to ones in Barrons</p>
