<p>is it a good idea to buy it?
also what is the difference between an international version of a psychology book and the U.S. version?</p>
<p>can’t answer about 3a solution manual.</p>
<p>international version is PAPERBACK and not hardcover. it is supposed to be identical to its US counterpart (photos, diagrams, pages, etc). the quality of the paper (good stock vs. almost newspaper thin, resolution of photos, and binding of softcover will vary, depending on the “publisher/printer”. also, you can’t really resell the book on amazon or half.com b/c they only recognize the original publisher by the ISBN. i’ve seen internationals listed on ebay, amazon, etc, but its not an accurate description, soooo, how are they selling it?</p>
<p>I bought it (Math 3A solution manual) and it helped a lot. I never went to class so this was a good way to learn how to do certain problems since the book is pretty unclear. However, the solution manual has TONS of errors, so be aware.</p>
<p>i recommend it, but yeah, look out for errors.</p>
