hellooo Hii,
Honestly I would say to have something be a part of your application that stands out. I didn't have any crazy extracurriculars or any insanely amazing grades, but instead I wrote my application originally. E.g, I wrote about how I believed that education was more than just about grades, but rather being able to use these skills to make changes, both big and small.
In the first introduction question, I also created an authentic idea of my childhood, and how I think my parents and childhood have formed who I am today. I think this sort of thing helps you to connect more with the board, and not just seem like a robot.
Don't stress too much, I believe that if you want something enough and write originally, it will work out. Sorry if this was unhelpful or a bit corny, just some tips I thought of off my head.
Goodluck!
