<p>I've been taking practice tests in my chemistry SAT II book, and found that there are lots of somewhat difficult calculations that are needed to be performed. How accurate are Kaplan's tests in comparison to the real test?</p>
<p>I think it’s more difficult than the real test.
Yeah, unnecessarily difficult calculations >"<</p>
<p>Okay that’s good to hear. Because the calculations are the majority of the problems that I am getting wrong on the practice tests.</p>
