How can I improve my chances?

Hi!
LMU is my dream college for film/cinematography.
I am a junior in high school and academically I am an average student. I have ADHD so obviously I struggle a little bit more. But I get B’s, 1 A, and a C in math.
My GPA is probably 3.17 or something along those lines. I don’t know if LMU Is dropping ACT/SAT during the time of COVID-19 but that would certainly be beneficial for me because I am obviously not the best test taker.

However! Outside of school, I am extremely active with music, screenwriting, sports managing and much more. I am In a selected choir and have even started my own A Cappella group that is completely student-run (and not affiliated with my school)

I have gotten the chance to sing in 4 different countries in Africa and Europe. Lead workshops with colleges and even sang to the pope (my choir, not me personally) I have been very consistent and active with my Extracurricular and continue to push myself and grow in many ways. I spend countless hours working hard on the things I love to do and have continued to grow and improve. I want to know how that looks to a college like LMU? How can I improve my chances in the possibility of attending in the fall of 2021? I know I need to improve a lot of stuff school-wise, but I have been continuing to do so.
