Does he like me?!?!?!?

he looks at me often and he sat behind me when we wrote our exam yesterday when there were like 6 other empty seats in the classroom and he could have sat closer to some of his other friends but he didnt. we dont talk to each other but i get the vibe from him that he might like me... the thing is though, im not popular and im not the prettiest girl ever. i have dark brown hair, brown eyes, glasses, braces, im 5'6 or 5'7 and i weigh 140 pounds... is it possible he could like me anyways? btw hes popular... btw once i was having a convo with one of my friends and he was sitting beside me (the teacher made a seating arrangement for our class) and i was looking up a word in the dictionary and i said what the hell to my friend cause the definition was idiotic, and he stopped a convo he was having with his guy friend so he could talk to me... in that same class i also noticed he would use the same posture and position i would when we were sitting down...
