I am preparing for exam. So far I have gone through PMBOK.

I have Rita's  6th edition handy, how ever I would like to know review of 7th edition.

Is the new versiion really helf full ? How can it help us with this latest pattern of exam?

1) Appriciate your help and guidance here. I really do not want to study two version of same book. Rather I will stop reading 6th edition and buy new one.

2) Have any one has passed the latest  new exam based on 6th version or Rita's book?

Thanks in advance.
