Physics Sparknotes

<p>Does anyone know how reliable sparknotes (test and information/material) is for SAT II physics?</p>

<p>Also, is sparknotes good for math IIc and chemistry?</p>

<p>I’ve been told that the practice tests are very accurate for physics.</p>

<p>I’ve been cheerfully using Sparknotes, but this post has me worried.</p>

<p>Should I get Princeton?
What makes Sparknotes so terrible, or Princeton so good?</p>
