There was something secret that Slavey Karadzhov, the main author of the book “Learn ZF2”, was working on in the last quarter of 2013. Now we can officially announce that he is proud member of the “Zend Framework Education Advisory Board” and he contributed to a certification exam very closely related to the content of the book. So if you want to pass the exam you have another good reason to buy the book.
Enjoy the exam and know that all sort-of-easy questions are from him. The difficult ones are from the core ZF2 project members and contributors :).
