Can I put it on a resume?

I’m currently a theatre major in college but I plan on switching paths. However, I only have a 3.0 gpa and a theatre internship. I did a lot of theatre shows during my first and second year (and by a lot i mean rehearsals 6 days a week 4 hours a day at least). Can I put them on a resume? Or is that just a cute extracurricular for grad school?

What area do you plan to apply to graduate school for?
