If you've already been accepted to Tufts (I assume this is where you are going), why would you deal with AADSAS? Just submit your final transcripts to Tufts. You don't have to deal with AADSAS anymore unless you want to go to a school other than Tufts and you still haven't heard from them yet. 🙂
If you're still waiting for another school, then uh, I don't know how many mailings they have. 😀 I'm still waiting for them to calculate my GPA, but with my luck, it'll take them about 4 months to figure it out. 😛
