<p>I'm looking to invest in a Rocketreview Revolution book by Adam Robinson. I can't find any 2006-2007 editions for under $75 anywhere online, but I can find the 2005 version for $20. So I was just wondering, is it worth spending the difference to get the newer editions, or are the books pretty much the same?</p>
<p>Thank you so much.</p>
<p>No, it is not worth spending an extra $55. It may not even be worth $20. Try to find it at a library to judge for yourself. If it isn’t available at your library, ask the librarian if she can locate it at another library and request an inter-library loan.</p>

<p>If you do end up needing to purchase it, you can sell it to someone else once you’re through with it to recoup some of the costs.</p>
