Hi Aymane,
You should be given a printed report with your score and an indication if you passed, prior to leaving the testing center. Candidates who will be receiving international mail can wait for up to 8 weeks. In my case, I received an email from Sun one day after I passed that instructed me to update or verify my mailing address so that my certification kit could be mailed. I passed the exam last Tuesday and, according to certmanager, the kit was mailed yesterday.
If you search this forum, you will also find experiences of people who are waiting a long time.
