If it mentions 11g in the title, it probably spends a lot of time on that. That would be a major distraction from MySQL.
Any MySQL book written in the last decade would provide good information, though may not have specifics of 5.6. Books older than that are iffy -- they might not even talk about InnoDB.
There is a long list of improvements in 5.6, but many of them are in remote corners that you don't need when first learning MySQL.
Unless you are aiming to take the exam, I would suggest that exam info might not be useful. Exams dig into corner cases.
What language will you use to access the data? Note, for example, that the first in the list below focuses on PHP:
* "PHP 6 and MySql 5 for Dynamic web sites" by Larry Ullman (Peachpit Press)
* SQL for MySQL Developers : A Comprehensive Tutorial and Reference by Rick F. van der Lans,
* PHP and MySQL (Video Training) by Mark Wandschneider who was a developer for Microsoft for years.
* High Performance MySQL (there are 2 or 3 editions -- they are different)
* (if you learn by example)
