<p>Hey, I have the 7th edition Barrons book for math 2, which is pretty old. Should i go buy the latest version?or are there no significant differences that it would be a waste of money?</p>
<p>Some person said that the difference between the 7th and the latest edition is the part describing calculator use, although I do not recall who said it and which calculator models specifically.</p>
<p>The differences between the books are marginal at best. They probably just fixed some typos. Plus, most of the practice tests are the same. If necessary, check out a book from the library.</p>
