I'm looking to present myself to a number of Specialization exams. There is quite a lot in the Community on the MCE, including some tips and mock questions. Does anyone have something similar for the Specializations?
All that is out there at this point seems to be Marketo's description of the exams: Marketo Certification: Additional Specializations
I'd research the topics for each Specialization and memorize the info. Much of it is in the docs and the forums.
I agree with Josh that the best approach is to study sections of the product docs that align with the area of specialization (topics covered for each specialization are outlined in that link you shared so that helps).
