I already purchased the voucher for part 2, I realized that there is not a 310-300A exam in www.2test.com. So how can the Prometic know that I am going to take the exam and to let me download the assignment?
My experience was that I found out my score at the Prometric site when I left the testing room. They gave me something indicating my score. As I recall, I couldn't download the assignment immeadiately because Sun did not yet have record of my passing Part I. After Prometric transmitted that information and it got into Sun's site a few days later, I was able to download the assignment.
It's been a couple of years, but that's what I recall.
