I am currently studying to complete the Enterprise portal development certification exam. Today I found this link that describes the different parts of the exam. Anyone who have taken one of these exams before knows that you get your result for the entire exam but also for each of the exam parts. That is what this link gives you, an overview of the different parts and what subjects each part contains.
You also get such information as what percentage each part is of the entire exam, which makes it easier to prioritize your studying in case of time restraints.
