<p>Basically, I'm taking Math II and Chem, both of which i hope to get an 800 on. I have PR books for each one from when my brother took the two tests (2007-2008 edition) with unfinished practice tests. Is there any problem with using a book that is one year old? I mean, it's not like chemistry or math changes, but I wouldnt really know.</p>
<p>I am also studying for chemistry and was able to borrow the Kaplan 2005-2006 edition. I have also just recently borowed the Kaplan (for chem also) 20007-2008 edition. In Barrons I bought the 2002 edition a while ago and studied from it and this week compared it to the 2007 edition my teacher had. There pretty much word for word. You have nothing to worry about! Good Luck!</p>
<p>I don’t think that using an older slightly older review book would be an issue.</p>
