Physics PR and Sparknotes Copies of each other !

<p>Hi Everyone. I have been studying for my Physics SAT Subject Test since the past few days using quite a few books including Barron’s, PR, Kaplan and Sparknotes. What I simply could not look over is the incredible similarity in contents between the PR Physics Book and the Sparknotes Online one. At places they are exact copies of each other, missing essential components together and son on. Have any one else felt that ?</p>

<p>And if yes who copied who ? Sparknotes online is owned by Barnes & Noble. So I believe they won’t use copyrighted stuff. But also the PR book is written by an MIT graduate. Comments.</p>

<p>Are you going through barrons thoroughly? From what I’ve heard from here, its got a hell lot of irrelevant information, and the relevant topics are not discussed in detail. So will you pay attention to the details? I’m asking because I did the practice tests of both pr and barrons and -preparing from pr only- I was unable to answer alot of questions from the Barrons. </p>

<p>As for your query… I really don’t think really matters. From what I know, pr and sparknotes are the best books for the test.</p>
