Consequently it seems to spend a lot of time on some topics which were heavily tested in the 1st SCWCD exam, but not tested as much in the 2nd version of the exam.
The book says "Complete update for the new exam", which is a lie. They forgot to update most of the book, leaving people digging into the specs to make sure that everything is correct. I've printed a lot from the specs and put everything in the book. Just look at the forum of the book, and you'll understand why people like me are angry about it.
