For you two who took the test less than a week ago, you have to give it some time. ADA has to audit your scores first (up to 2 weeks) and AADSAS only dumps in new scores once a week. So 2-3 weeks is probably normal. And keep in mind this is the DAT busy season. If it's faster, wonderful. But I wouldn't start worrying until a few weeks has gone by.
As for taking it in December, your scores should have been there when AADSAS did the first DAT update a few weeks ago. I recognize your username from the pre-dent forum, so I assume you know that your actual scores will never show up. So hopefully you're not waiting to see your numbers. All you will ever see are a couple of dates. Once 'Date Received' shows up, you're good to go. The process is actually pretty smooth. So if you're still not showing a date received, I'd verify things on your end and then start calling. As long as you selected at least 1 school when registering for the test and you entered your DENTPIN and date of birth correctly in AADSAS, you should have a date received showing.
