Observation. I'm told that some classes (e.g. physics 101?) have hundreds of students in them. If each student needs/would benifit from 10 minutes of your time per week per class then I don't see how there is enough time for a proffessor to give that time.
This is worth addressing, since it may sound a bit scary, and it shouldn't.
First, note that there is no "physics 101" at MIT. Rather there are three different versions of "physics 101". At MIT
everyone takes freshman physics and freshman calculus, but not everyone has identical needs (the music majors -- yes, there are some -- don't need as intensive an approach as the physics majors). So, there's 8.01, which is regular mechanics. There's 8.012, which is the heavy-duty version intended for physics majors. And, there's 8.011, commonly called "physics for poets", which is a little lighter. Different texts, different profs, different approaches (and forgive me if I've got the course numbers wrong; it's been a long time).
Now, with ~1000 kids in the freshman class, and
everyone taking freshman physics and calculus (and a chemistry class, and freshman humanities) there are, indeed, hundreds of students in some classes. But the classes are structured the way they are at many universities: There's a lecture once a week where everyone sits and listens to the prof talk, but there are also two or three "recitation sections" each week. The recitation sections typically have a dozen students in them.
When I was there, the prof for the class typically led one recitation section, and grad students led some of them, and other professors led some of them. My recitation section for calculus, for instance, was led by Sigurdur Helgason, a prof whose actual area of interest was something in differential geometry. The lecturer for calculus that term was Gene Kleinberg, who was one of the clearest speakers I've ever met. (Of course, there was another section of the calculus class which was lectured by George Thomas, of whom I'm sure a number of people reading this have heard.)
Now, when you hear "grad students led some of them" I can imagine you're groaning. But seriously, these are freshman classes we're talking about. The grad students who led the sections in my physics classes were eminently capable of explaining the material -- at that level, they're perfectly qualified, and they may even still remember what it was like to go through it themselves.
So, the chimera of limited access to the prof in the freshman classes really isn't something to worry about. And in later classes, after you've gotten past the neck of the funnel, the class size shrinks dramatically and those same profs who seem so distant (well, 50 feet or more away!) turn out to be approachable and helpful. Gene Kleinberg, who did the lectures in my calculus class also taught a seminar I took on hyperreal calculus that same year. The seminar had about 10 students in it, and he was very happy to spend time trying to explain the absurdly advanced concepts it used to a confused freshman.
