So I signed up through the ADA to take my DAT. I still haven't gotten my letter so I can contact the Prometric people. I heard that I could do this all on the net and not wait for the letter to get here. The only problem is that I'm Canadian so on the website it asks for SSN and I don't have one. Instead, I use my SIN but the site won't accept this. Anyone know what I can do?

Also, how long does it take for the letter to get here (plus I live in Toronto so I can imagine adding a week or two onto that)?

It took me about 2 1/2 weeks to get my letter. I'm sorry but I can't help with the Canadian thing.
