What does it mean if a girl turns around to look at you (in class)?

In my case, the girl sits in my right-front. I'm 95% sure that she looked at me (according to my peripheral view). She did that while we were taking a test.

Actually, it wasn't a test. We had to write our own feedback about the class (it's the end of the semester). So we weren't evaluated on it.
