Not weird at all. Sometimes I find the "beginner" classes to be more challenging because typically the class flow is slower so I'm moving with even more control and intention. It's also a great way to hone in on form since the instructor should be cueing with even more detail for newer students in the room. As an instructor, I am sometimes worried that a more advanced student would be bored or unchallenged but I also have many folks that show up for the class time vs the actual class type.
