<p>I'm using Sparknotes and PR for the math iic
and the practice test scores for both of them seem to be consistent with each other, but i wonder what my real score will be.
How accurate are these anyway? Does anyone have a clue?</p>
<p>I haven't used the Sparknotes IIc, but I've been sadly disappointed with other Sparknotes book. (The Sparknotes ACT book was pretty pathetic.) The PR book is OK, but the practice tests aren't particularly accurate. I'd say they hit the mark about 80% of the time, but the tend to be written more as examples of the PR techniques than the actual test questions. Scores on PR tests are a little unpredictable, but in general, I'd say they might be a little higher than your actual score might be.</p>
