In March 2013 I passed OCEB exam and became OMG Certified Expert in Business Process Management. This exam mainly focuses on BPMN 2.0 language and Business Process Management knowledge, methodologies and techniques.
Apart from the workshops that I attended organized by training provider (Altkom + Topaz) I also prepared myself individually. Mostly I used two resources: a book and free test questions.
In terms of resources for OCEB exam series there is not much choice. There is only one book on the market OCEB Certification Guide:Business Process Management. After I read it I found that this book does not go much into details but on the other hand it is on the sufficient level of details to pass the exam.
I didn’t want to buy any test questions so I used sample available for free on http://www.businessprocessincubator.com/OCEB website (look for a “Free Practice exams to test your BPM knowledge”). I think those questions are a little bit harder than those on a real exam. This is a good tool to evaluate your knowledge before the exam.
Good luck with your studying!
