Hi,
Is there anyone from the certification team that can help? VUE Pearson, sent me today a email saying that the testing centre would not be able to deliver your exam due to an unexpected circumstance which was due for the 31st of Dec which I booked on the 28th of November.
I was planning to update my 3.5 to 4 certification without taking the "whats new" course.. The earlist VUE Pearson can rescheduled is the 7th of Jan. 
Thx
John
