Most accurate

<p>What is the most accurate indicator of score in your experience, Sparknotes or Barrons?
This is really really weird but I'm getting -4's on Barron's practice test and -20+ on sparknotes o_0.</p>

<p>This is for SAT Chem, but I would like to know generally for all of them..</p>

<p>Barrons is pretty accurate in general but I have no clue how it is with chemistry.</p>
