<p>Another thing to consider is that in some of those large classes, (econ, poli sci that I’ve attended in the last few years) while the enrollment might be 100-150, often only 2/3 to half of the students will show up to class!! (except for review for exam classes etc) So there is actually more opportunity for those who do want to get the most out of their education by going to class to interact/ask questions etc. I think in the STEM large classes, a higher percentage of students attend classes.</p>
