I'm happy to announce that I sat the exam for the Microsoft Partner Network BizTalk Technical Competency Assessment for Application Integration and passed. I'd like to make mention of some resources I felt really stood out in helping me prepare for the exam:
BizTalk 2010 Patterns by Dan Rosanova is based on BizTalk Server 2010 but a lot of the fundamentals still apply.
Microsoft BizTalk Server (70-595) Certification and Assessment Guide (2nd edition) by Johan Hedberg, Kent Weare, Morten la Cour has been updated to include BizTalk 2013 and as far as I know the only study guide that covers the latest release of BizTalk.
