2011 BEC Becker Text Book

I just received 2011 Becker BEC textbook, and I am surprised how different it is from the 2009 version. I purchased a whole set of Becker Review back in 2009, but I didn’t study them. Now I tried to study again and just ordered BEC 2011. When I compared the new version to the 2009 one, I see the new 2011 version completely deleted a whole chapter in 2009 which discussed company structures, such as partnership, LLC, corporation. I compared the AUD 2011 to AUD2009, which are very similar…but the BEC book just looks like a whole new book…my question is: Does the new CPA exam stop testing on topics like company structures? Have the CPA exam on BEC changed significantly in the last couple years??? Thanks.
