<p>While I have managed to get a 4.0 for a single semester, it is pretty rare occurence (not to honk my own horn). I am yet to hear of anyone here who has sustained one for four years, and it seems like it would be more contingent upon the vicissitudes of fortune than actually ability (though both would certainly need to be present!). I know a few students who are smart kids, but who have never managed to get a single full-fledged A. I have also been in a class where NO ONE got an A, though three people got A-'s. </p>
<p>Wow, I hope that doesn’t sound too stark.</p>
