Me? Smart?

Two people today asked me if I was taking anatomy and physiology, a rather difficult science elective at my school. I would think my classmates would be able to tell that I'm not that smart by now. X'D I mean, I generally get As and Bs, but I don't really try as hard as I should. Anyone who's ever worked with me during a group project should know that I'm not the brightest, except those multiple times where I've been the only one to actually work...that happens way too often. ;_;

Sometimes I think it's because I wear glasses because supposedly the glasses=genius stereotype still exists at my school. I'm not saying I dislike being considered intelligent, but having a vision problem does not make me smarter.
