Yeah, I think it’s difficult to make a general statement here. The only CC class I’ve taken was a summer school class at a satellite site of a CC doing geometry in like 9th grade. The class was basic and the teacher was meh. My stepdad taught chemistry at a CC, and after completing a chem minor I probably knew more chem (or chem theory) than he did (he graduated in the 50s). He was probably a decent teacher for the chem for firemen and cops classes he taught.
There are great teachers and bad teachers for all kinds of classes, but as long as the book is good that’s where I think real learning takes place.
