Help with homework and flirting

This guy called me about the physics homework but there was "flirtatious joking" and he asked me questions unrelated to the homework while we we're on the phone. Could that be a sign that maybe he's possibly interested in me?

Oh and I should point out that the none homework related questions he asked me were still in some way related to school. Just thought I'd point that out so people knew he wasn't asking questions like what;s your favorite movie or something like that.
