<p>i'm going to take the next october sat subject biology and i just took sparknotes biology test online and scored 740. How accurate will this be on real thing?</p>
<p>Not very. You will want to take a full length test under real time conditions.</p>
<p>^Well, the Sparknotes tests are full-length tests under real time conditions. </p>
<p>I’m really not sure how accurate they are, but I don’t think they’re too far off from the real thing. Take a practice test from the Official Subject Test Guide, or from another prep book like Princeton Review.</p>
<p>to sort of piggyback on this thread instead of starting a new one…</p>
<p>how accurate are the princeton review bio subject test practices compared to the real one?</p>
<p>Sparknotes are very unaccurate for Chemistry atleast. I got a 590 on the Sparknotes after prepping hardcore for a few days (PR I got 770).</p>
