> If it’s a small group, I can actually learn everybody’s names, get to know them, personalize the material more and spend big chunks of the class just answering your questions and starting discussions based on them.

I went to a relatively small private engineering school. It made a world of difference in my education knowing the professors, and having them know me, especially given that with small classes the professors offered office hours where I could come and discuss the material that was covered during class, as well as problems I encountered on midterms.

I still remember nearly all of my professors, fondly, precisely because of the dynamic small class sizes allowed for.
