Serialization was removed from the objectives when the number of questions were reduced from 72 to 60, so if your center says that there will be 60 questions in the exam, then most probably Serialization won't be on the exam. Still if the people at the center know in detail about the exam, they will be able to tell you if Serialization will be there or not. Generally people at prometric center don't know much about the exam details (at least the prometric centers here are like that), so the number of question trick should help you...
Thanks Ankit for this updation because i was also wondering help from Prometric center
, because 2 days before they did not even know that the number of questions are reduced from 72 to 60
