Is this girl hitting on me or being friendly?

Ok so I just started my new night cl 2 weeks ago(its a 7 week cl) and this fairly attractive girl out of no where just randomly asks me how I did on my test, I mean I don't know her at all whatsoever and she was giving me deep eye contact and smiling, is this being friendly or is she subtly trying to hit on me or what do you all think?
