If you already have the old SuiteCloud Developer cert, then you take a "delta" exam which is the difference between the 2 exams. You have to sign up and take it just like you would any other cert test. Suitetalk has 2 search types that they want you to know searchMore and searchMoreWithId and pretty much everything related to workflows.. like why is this workflow wrong? or which phase would you like a record on.. stuff like that
