<p>In reality, how big are these classes? I saw on the Cornell website(a link to class sizes), and I was shocked to see the introductory chemistry classes have around 500-750 students. Is this real? How do these people fit in like an auditorium?!</p>
<p>And in general, how big are first year classes? ThankS!</p>
<p>For required/popular intro classes, like biology, engineering math, chem, the classes are gigantic. And they have built the appropriately sized auditoriums.</p>
<p>Well, not always. Most large classes have multiple lectures/time slots. The total enrollment will still be quite large, though. </p>
<p>Large introductory classes actually work very well in the sciences. It forces professors to be more organized and hold lots of office hours, you have a much larger support group of classmates, and you get close interaction with a lot of TAs and graduate students. (I spend the first couple weeks of classes shopping around for good TAs.)</p>
<p>You get used to large introductory classes, and in fact, I like them.</p>
<p>They are efficient and work well with self-discipline.
Science classes don’t require much professor interaction for introductory material and so it doesn’t matter if you are teaching it to one person or to 500.
Plus you get sections which are where the real “learning” takes place.
Also, it’s easier to skip one when you just feel the need to prioritize your time.</p>
