Replying to follow as I am wondering the same thing! I know from other threads (and also have heard from schools), that it is wise to submit your Optomcas application ASAP, even if you haven't taken the OAT. I also have heard that some schools (like Salus) sometimes offer interviews before they receive your official scores. I take mine on September 3rd, and from there I think I am going to email my unofficial scores to the schools I am applying to so I can hopefully speed things up. Good luck with everything! 🙂
