How do you submit them to AADSAS? If that's the question, you don't submit them. AADSAS will receive your scores around 2-4 weeks after you take your test.
You don't. AADSAS does. You select schools when you register for the DAT. You then select schools when you submit your AADSAS application. ADA hands the scores to AADSAS. AADSAS hands scores to the schools. Back in the day you might have had to submit directly to schools yourself, but these days I can't think of any that want more than what AADSAS delivers.
