First of all: could you please stop with always quoting the complete post. It has no added value, because it's just the 2 of us discussing so it's normal that your reply is a reply on what I said. And if you want to refer to a specific part of someone's reply, just quote that part instead of the complete post. Use the quote-functionality wisely. Thanks!
Secondly, do I understand your situation correctly? You purchased the assignment through Prometric and you'll have to submit the assignment through Pearson VUE (because prometric is no longer the test delivery partner of Oracle)? If that's your situation, take a look here and more specific to the posts of Dennis Grimbergen (he was in the same situation as you).
