Ok I'm not sure how far you are into applying, but first you should fill out your AACOMAS and get that submitted ASAP. I'm sure you've already done that, but if you haven't that should be the number one priority. If you have already submitted and you are complete but haven't received a secondary application, I would encourage you to give Dr. Weir a call to express your interest in the school. Since you have been a missionary, it shows you are willing to serve the under-served, which is important. WCU COM is EXTREMELY accommodating to "non traditional" students, so your background will really help you stand out! 🙂 if you have received a secondary and turned it it and still haven't received an interview, I would still give Dr. Weir a call or shoot a quick email. It is important that you express your interest in the school and show that this is where you want to be.
I hope this helps and I hope you get that interview soon!! Please let me know if there is anything I can do to help!
