Can practice material become outdated?

<p>My sister bought a CollegeBoard blue book in 2011 and amassed a large collection of SAT words in 2011, all back when she went through this. I'll be using all her practice material. Good idea or a complete waste of time?</p>

<p>Excellent to reuse her book, unless she wrote all over it/took the practice tests out. You WILL need to write in the book, so if she scribbled in it you will need a new copy. If not, just use her stuff!!</p>

<p>Thank you, and bump</p>
