I understand this but why is she doing this everyday?

I have two classes with this girl, and this girl as soon as I come in the room for my first class, she stares at me as soon as she sees me? Why does this girl do this everyday? Kinda confused, ngl, so if anyone sees this, can you please help?

And also in the second class we sit together with two other guys, and when she needs help she asks them and never asks me? Does she have a problem with me or what?
