is he interested in me?

ok theres this guy that is in one of my college classes, he's pretty cute. our professor told us to give a couple of people our numbers so if we miss a day we can call or txt someone and ask for hw or whatever. everyone just like turned around in their seats and asked people tht were close to them for their numbers. but this guy walks across the room to me and asks me for my number. everytime he comes into the room he looks straight at me.. and one time he texted me for the hw and kept carrying the conversation to other stuff like what im interested in and another time i txted him asking for the hw and he starting asking me how i was doing and told me he's gonna take me for a ride on his bike...but when he's in class he never talks to me, he just looks at me. he's not one of those shy guys cause he's always talking to other people in class ... idk is he interested?
