Is the official US History blue book realistic? Will I get at least a 700 tomorrow?

<p>I’m an international student who had zero prior knowledge of U.S. History. I’ve been studying with REA and Direct Hits. I took the official practice tests from the blue U.S. History book yesterday and today and I scored 730 and 760 respectively. I wanted to know if these tests are actually realistic. Should I expect to get at least a 700 tomorrow?</p>
