Is this a sign that she is also interested or is she simply using me as an ego-boost?

I know when I'm interested in a guy, and I know I am going to see him, I may more of an effort. Whether that's wearing nicer clothes, or making sure I have my hair and makeup done - just something a notch up from what I would normally wear. Like, I'm interested in a guy in one of my classes and instead of changing into yoga pants before class, I stay in my work clothes (which tend to be girlie and soft since I work for a spa). But the days we don't have classes I'm back in my sweats.
Compliment her. Ask her if she wants to grab coffee after class to discuss [insert upcoming assignment] and once you get her in a more social setting start breaking the ice and get to know HER better. If she keeps the conversation going and returns the questions, or gives open ended answers, she's probably diggin ya.
