Is Sparknotes helpful or a time-waster?

<p>What do you guys think about Sparknotes (<a href="http://testprep.sparknotes.com/%5B/url%5D"&gt;http://testprep.sparknotes.com/&lt;/a&gt;) for test prep? I'm still vacillating between the SATIIs and would a quick read of their online books, then a practice test be helpful in deciding? Or should I just decide, buy the actual prep books, and do some "hard-core" studying? </p>

<p>I'm not sure why I'm even thinking about the SAT "Subject Tests" when the SAT is less than a week away...</p>

<p>it is gd as an addition but not as your main resource/material... do thye give free tets preps? i think only the content... i think itz more useful when decidin wat sub to take so can skim thru the syll quickly... for proper practice, hit the bookz man..:D</p>
