I think it's possible, assuming your school draws on a non-representative population in terms of socio-economic status. Your school probably has few or no kids who were exposed to drugs or (much) alcohol in the womb; most of them probably experienced enriched environments as toddlers; most of them probably have educated parents with relatively large vocabularies; and many of them probably come from families that value education. That's before we even get to the possibility of skewed genetics due to all those engineers!
