I Need Advice: Undergrad Not Studying LA but Wants to Pursue LA Grad School

Hi! This is my first reddit post so excuse me if I'm doing it wrong. I am a rising senior in undergrad with a Sustainbility in the Built Environment major and a Landscape Architecture minor. I really haven't gotten very far in my minor progress. I've taken Site Analysis and Intro to Landscape Architecture, but I still feel like I do not have much experience at all. I have taken a few ArcGIS courses and one AutoCAD course too. I am really considering pursuing a Landscape Architecture Graduate degree, but I am unsure what I should be doing now to get there. I have applied for a few internships, but I am not sure I will get them. What skills should I work on, and what else should I try to do to boost my resume before applying? I'm open to any other general advice you may have. Thanks for the help!
