i am not a prof. at florida but at a similar place.
we think we have very few math majors, really only a handful, but we recently learned that relative to other places, we actually do not have so much fewer than average.
the paucity of math students puts pressure on those of us who try to elevate standards, because the prevailing way to increase numbers is to lower standards.
i am willing to answer any question, at any level, but i believe it is my duty to try to raise the level of the discourse to something like what is current at good schools elsewhere, and to also let students know what that level is.
some people say however that even at top schools the level is way down from the 60's. of course this is not the view of current students at top schools. they think they are better, just ask them.
perhaps one reason harvard has fewer math majors is they do not offer a spivak style intro to calc course, the one for math majors. they think they have no audience for it.
i.e. everyone who goes to harvard has already had intro calc at the AP level, which sadly is usually far below the spivak level.
thus students get into harvard or stanford, etc,, with woefully inadequate preparation in calc and then are plunged into a course designed to follow a spivak course, even though they have not had the spivak course first.
stanford for example a few years ago offered a course for good entering students out of voloume 2 of apostol, but no course out of volume 1 of apostol. the attrition rate was amazing. why they did not seem to care i have no idea.
a very few top schools still offered a spivak type intro to calc course recently, like chicago. some state schools also offer the course but do not attract the students that go to top schools.
another current phenomenon in grad schools in the us is a preference for american students, even if they are less well prepared, an attempt to reverse the trend of few native scientists. this forces a lower standard on the program in order to maintain these stduents.
I.e. the response to a low participation by certain groups in the US is always the same: instead of investing the money needed to raise the level of qualifications for that group, we just lower the standards of admission for that group.
thus there are special scholarships available for american citizen math grad students that insure their admission and support, over better foreign students.
notice this is not the case in basketball, where better players from europe are welcome. it is embarrassing to have higher standards in sports than in mathematics but there it is.
