<p>For example, is it better to buy a 2010 macroeconomics book vs buying the cheaper 2006-2007 book? Or are they the same thing? </p>
<p>(I'm taking the Calc/Bio/Physics/Eng Lit/Macrecon exams -- does the publishing date matter for any of these?)</p>
<p>Thanks.</p>
<p>I know that it does matter for AP Computer Science, since the College Board dropped AP Computer Science B last year. It’d be pointless to study for non-Computer Science A material.</p>
<p>The date really does not matter because the content doesn’t change. Sometimes there are changes to the exam i.e. the synthesis essay on English Language, or slope fields being added to Calc AB, but changes don’t happen often. The newer editions are basically the older ones just reprinted with maybe some small format changes. I have a 2003 US Gov review book and I compared it to a 2010 book. They are almost exactly the same.</p>
<p>It doesn’t really matter. I highly doubt that it’s not gonna be the difference between passing/failing.</p>
<p>awesomee. thanks!</p>
<p>slope fields are the SO GAY</p>
<p>^I am really hoping there is a slope field on the AB exam this year. That’s an easy 9 points right there.</p>
<p>haha oh my gosh dude what are you talking about!! slope feilds are the worst thing that has happened to humanity since godzilla</p>
<p>You just plug in points to the differential equation that they give you, then draw a slope at each of those points. Then you just solve a differential equation, where points are given out like candy for each step you complete. Easy points. I will be extremely sad if I don’t see one this year.</p>
