Thinking about applying

So I’m a pretty atypical applicant- I recently graduated with my Masters in clinical social work and am interested in applying to the dramatic writing graduate program. Part of the application asks for our professional creative writing hx/publications…Which I have none of since I’ve spent the last 6 years studying social work. Is this problem?
Additionally, I’m a good writer and I know my voice, but I am no expert when it comes to structuring a story or a screenplay, is this a huge issue? Would appreciate honest answers!!

Thanks :slight_smile:

Clarification- I do have a creative writing portfolio, just no PROFESSIONAL experience with creative writing or publication.
