<p>How similar are the new Princeton and Barron review books to their predecessors?</p>
<p>i.e. If I have one from 2008 do i need to get the 2010 version or are they virtually the same?
(If it matters im inquring about the chemistry and biology sat II tests specifically).</p>
<p>I’d think there wouldn’t be that strong of a change in the material itself, but rather the practice tests. Curves for the subject tests sometimes change around year per year. But other than that, not a HUGE difference (though I’d personally just go with the latest book for new information regarding the SAT II format and other specifics itself).</p>
