Does anyone else feel like an imposter/doesn't belong in their classes

It's quite a strange feeling but whenever I'm taking classes I feel like I don't belong there, like I'm just pretending to be a student that has that major. I was majored in nursing for about a year and a lot of the classes I felt like I didn't belong and recently I swapped my major to music (big switch I know) and had my first classes yesterday and felt the same way. Maybe as I take more classes I'll feel like I belong, but it almost feels like I'm an imposter in class.
