<p>Hello, I'll be taking AP US History this year with the new curriculum in place. I was eager to get AMSCO as an on-the-side prep book to read throughout the year, but am reluctant to pay that much for it. My question is, would it make a difference to buy the 2015 edition of the AMSCO book instead of the previous edition? Would my exam score be lower, possibly, if I choose to go with an older AMSCO edition? Any help is welcome, thanks.</p>
<p>Doubt it.
It’s not like the writers of AMSCO know what’s going to be on the new test any more than we do for the most part.</p>
<p>@shinchang I seem to agree, I think the content is the same just the structuring of the test is different.</p>
