I submitted AACOMAS mid-June (the day MCAT scores were available online) and received my first DO secondary on July 9th from PCOM. By the end of July I had received all of my secondary minus LECOM which came first week of August and NYCOM, which didn't come until November. OUCOM came on July 26th and I had an interview invite from them for October 8th which I cancelled, but I am not sure exactly when that invite came, however I remember it was near the end of August/beginning of September. I didn't apply to AZCOM, sorry. My main advice is to get the secondary back in the mail the next day after they come. Pick up your mail, fill out the secondary that same night and drop it in the mail the next day. Do not procrastinate. I had my first interview in mid August at NSU. Good luck!
