Hi :-)
What is the correct publishing data for OCA/OCP Java SE 7 Programmer I & II Practice Exams (Exams 1Z0-803 & 1Z0-804)?
Amazon says 22 March 2015, McGraw-Hill says January 31, 2016
The publisher's date will (always) be more accurate than the one on Amazon. Certainly for books which aren't available yet as the publisher is very closely involved with the complete process of the book (writing, editing, and so on).
