Intended major

Does it matter whether to list the 3 most intended majors on the application? I kind of have an intended major in either math, computer science, or theoretical physics, but I’m by no means completely decided on one thing to get a degree on.
Does listing all 3 intended majors as “undecided” make you look bad or have any effect (negative or positive) at all, or is it there just for curiosity?
FYI, on the 300-word essay about what areas I’m interested in I talked about why I like math, compsci and theoretical physics though. But I didn’t specifically talk about my past experiences which they ask to talk about if I have an intended major, whereas for “undecided” option I just have to talk about the fields of study that I find interesting.
Thanks!

Personally I’d put undecided as your first choice and then put CS/physics/math as your second and third. I’m also undecided, and that’s what I’m doing. It probably doesn’t really matter, though, since they’re just standard questions. The essay about your interests is definitely more important.

Thank you! I’m gonna do that
