<p>I barely finish the test within the allowed hour, and this is making me nervous. I do decently, I guess. I got a 710 (could've gotten a 740 without the stupid mistakes) on the Princeton Review test and a 720 on the Kaplan diagnostic test.</p>
<p>However, I would really like some time at the end to check my work, so is there anything I can do to improve my timing? Any little tricks for quick calculations? (I think the calculations are what trip me up the most.)</p>
<p>Also, a friend told me that if I get a 720 or above on the Kaplan diagnostic test, then I am decently prepared and will likely score higher on the real test. Can anyone agree with this?</p>
<p>Out of the three practice books (PR, Kaplan, Barron's), which book's practice tests come closest to the difficulty of the real one?</p>
<p>I'm studying at least two hours a night for this test in June, and I'm already worried sick about it. I want a 750+, since I'll most likely go into a science/medical field, and, well, I just feel obligated to score well.</p>
<p>I heard Princeton Review is exactly like the real test, but maybe I am wrong.</p>
<p>Well, that's a relief, although I've heard that Kaplan's is closest. All I know is that Barron's is the hardest.</p>
<p>Yep Barron's is by far the hardest. Just keep practicing and you should be able to get your time up.</p>
<p>I studied with Kaplan's for about a week before the May SAT II's - I was scoring low 700's, and when I took the actual Chem exam on Saturday, I found it to be much easier than the practices - I predict high 700's for myself.</p>
<p>As for finishing quicker, I'm afraid I have no tips. Best of luck!</p>
<p>Use Barron's--it covers everything and the tests are fairly accurate. I got 720-740 on barrons and 760 on the real thing. I found barron's really helpful for complete understanding, for chem at least. Be wary of the other ones though like Us History.</p>
<p>Ah, thanks for everyone's advice. I'll definitely use Barron's for the rest of my studies, since I finished the Princeton Review book in two days and found that it really didn't cover anything in-depth.</p>
