Sorry to hear about your attempt. Anyway, you can always try again and be better prepared. I did not want to rush to do the exam for fear that I was not well prepared. I don't think that there is a new PMBOK version because it is the same for the new exam as well. However, there are 8 new tasks added and there will be some amount of change particularly with regard to Stakeholders and their responsibility. In fact, I am not even sure who is responsible for the signing of the Project Charter. Is it the sponsor or the Stakeholders chosen by the PM to be part of the Sr. Project Team.
Please share your experience about the exam and your preparation so that we can learn and make changes to the strategy and approach while preparing for the exam.
