first, excuse my english, not enough perfect.
I've prepared OCPJWCD 5 in the bates and kathy's book. But now I want to pass OCEJWCD 6. By what I know, the Lyons's book is the only and best one to do it.
So, the question is, what parts of the book do I have to study to "upgrade" my knowledge from the fifth version (what I've learnt) to the sixth one??
