I've just received the email from OCP Team .. I passed :-)
The score is not so high (134) and I'd like to know where I can improve my knowledge but unfortunately it is not possible.
Here my timeline:
30 June 2011: upload assignement
12 July 2011: essay
11 November 2011: I received the email
Anyway I often checked the Pearson Vue and CertView sites ..
On Perason VUE and I've seen 2 days ago (09 November) that the score report about the assignement "1Z0-848: TRANSITION (VOUCHER ONLY) .." reported that I passed the exam (even if the status was and is still 'taken'). The item "1Z0-866: Java Enterprise Edition 5 Enterprise Architect " still has the status "taken" and the score report says that the assignment is still in process..
About the CertView: the OCP Team wrote in the email that I have to wait a couple of weeks to see my certification status updated.
