is Sparknotes any good?

<p>So is sparknotes SAT prep good or should I use another source?</p>

<p>Sparknotes is really helpful; I learned a great deal. Just give it a shot. I doubt there is anything better than Sparknotes. Many members of CC refer to it. So just try it out.</p>

<p>I'm not sure about how helpful it is for math, but it helped me a lot with critical reading and even US History Subject Test. However, if you really want to up CR score, use Direct Hits book.</p>
