The scope of SCEA is certainly less well defined than Sun's other certifications. However, this is always going to be the case when you're dealing with decision making, as opposed to API usage. You just have to be a little more disciplined, and resourceful, when it comes to managing your time and sourcing information. If you stick to the topics covered in the
Part 1 objectives, you won't go far wrong.
However, one criticism I do have regarding part 1 is it's excessive focus on
patterns relating to previous releases, as many of them are now obsolete. Just bear that in mind when you move on to part 2.
