<p>Alas, the Blue Book are the best simulations that we’ve got, but they are a whole bunch of things going on during test day that are very, very hard to simulate at home: the proctor being a jerk, the stress of taking a test that ‘counts,’ new question approaches that the SAT uses to create hard questions, those chairs designed for right handed people, etc.</p>
<p>In general I think the stress tends to push scores down, especially for high performers who are acutely aware of the importance of their scores. I would encourage everyone to track their pacing and see if they speed up during the actual test as compared to practice.</p>
<p>If you want a short want to get a sense of your performance we have a [fifteen</a> question math diagnostic test that predicts your score](<a href=“http://www.testive.com%5Dfifteen”>www.testive.com). It’s no substitute for the Blue Book, but if you’re time crunched people say it’s a good predictor.</p>
