<p>Does the edition of the book I buy really matter? Like, is there any exam that has chaged that an old book wont work for?</p>
<p>I have 2 versions of different year of 5 step to a 5 Psych.
They both have the same materials but maybe move the organization a bit.
They both have the same 2 practice exams. Moved the question orders.</p>
<p>I never go in depth to know if there is any difference. But generally, I think they are basically the same material with a little different organization. So yeah, edition years do not matter very much.</p>
<p>I think it depends on the subject, some of them have been updated a lot more than others I heard?</p>
<p>Like which ones have changed a lot?</p>
<p>I recently found a 2002-2003 edition AP U.S. Government and Politics review book from Princeton Review at a book sale at the library for only 50 cents and compared it with the current review book. I was surprised to find that the vast majority of material was exactly the same, in spite of 7-8 years of time passing. Some organization had been changed, but the bulk of the material was the same. Save yourself some money and buy older editions; the majority of stuff in there doesn’t change much from year to year.</p>
<p>I really believe that edition years do not matter.
I have a few experience on Psych, HuG and ES. Those edition years’ material are the same with organization a little different.
So I’ll just generalize for myself that edition years do no matter.</p>
<p>However, you can do a little experiment with subjects you want to know by using Books Google.
I tried. For example put in AP Human Geography. I check out 2 Barron different edition (2008 edition & the how to… edition). They are previews. I see that graphs, charts, materials are the same. With only the summary section is different: 1 is at the end, 1 is at the beginning.</p>
<p>So now you can google books those that you want to know.
Usually there is a some pages preview.
Good luck!</p>
