I agree with all that's been said. Do well on the DAT (which you will). And DO send your application in early. AADSAS really messes up with some applicants and those delays can take a month or more to get the right stuff to the school. The best way to eliminate that possible error damaging your application is by you getting your application in early enough to negate any potential error that AADSAS might make.
Submit the appliation in May, take your DAT and do well in August, and you should be fine. The ADA is really quick about getting those DAT scores to the schools (5-10 days usually). The bogdown, if there is one, will be with AADSAS.
Good luck!
