What makes people think someone's smart?
Demeanor, dress, behavior, etc. I'm asking this because everyone thinks I'm really smart and I honestly have no idea why. I don't say this to brag, I genuinely have no idea why people think that. Like apparently I'm thought of as one of the smartest people in school, (I get called stuff like that by people, whenever someone gets the best test score in class, nearly the whole class guesses it's me aloud, and we're in Pre-IB) but my grades aren't the best(I get A's but B's sometimes slip in), I sleep sometimes in class(I'm not sure if anyone notices), and I'm not a really serious person. Can someone please clarify why to me or at least help?
