Do Test Prep Editions Matter?

<p>Hey everyone, I'm somewhat new to the realm of SAT prep workbooks and I was wondering if always opting to buy the latest edition of a workbook (i.e. Grubers SAT 9th edition vs. 10th edition), if the comparison is only differentiated by one edition or so, always the best option? Does it really matter ? </p>

<p>thanks.</p>

<p>i don't think the actual tests would be different, but the latest edition would have a lot of the corrections/typos fixed</p>
