UF overcrowded?

I see people on this thread commented about the business school, which my daughter was accepted to but when we toured they did not offer a business school tour that day so we only took a general tour. My concern and hers about the business school is that it seems that kids don’t go to the introductory business classes and just watch the lecture online, is this how the business school works? I know it’s s big university but this seeems off to me that it’s just online classes with no interaction/discussion, can anyone comment on this?
