If you are just sending your application thru AADSAS, it will take them 4+ weeks to send your application to your selected school....so pay and deliver ASAP!! Don't procrastinate, waiting for DAT scores. Just fill in your application with the date you are taking the exam. When you take the DAT, ADA forwards your scores dirrectly to the schools and it takes like two weeks. I believe ADEA creates an account for you as soon as you have stuff coming in and start an app.
