Grab an unofficial transcript from all the institutions you have taken classes at and be ready to type them into your AADSAS application exactly as they appear on the transcript, the grade you received and the amount of credits/semester hours. Other than that, AADSAS will wait for the official transcript to arrive and you E-submitting before verifying any coursework. You will want to triple check everything before E-submitting for final review by the people at AADSAS.
