Level II 2009 vs. Level II 2008

Hey everyone, Does anyone know if there were big changes made to the Level II 2009 CBOK from the 2008 CBOK? I’ll be taking it for the second time in 2009 and want to see if its worth it to buy the Schweser books or study from the 2008 Level II Schweser books? All I want is the online question bank, I don’t need new books if the material is 99% the same. Any help would be great. Thanks- RJS
