Would it feel less like bragging if the question were couched differently? Rather than something you took pride in, perhaps something you felt you accomplished (without pressure to look for things that others didn't accomplish) or something you simply enjoyed doing? If I were the instructor, I would be going for examples of those, rather than examples of pride - pride isn't known for team-building. If you feel like you can, you might talk with her about that.

I hope you enjoy the practicing and the results!!! *hugs*
