By the way, the term "university" comes from the word "universal" and was a group of colleges that banded together. The United States tends to follow the European pattern where we have a "college of arts and sciences", "college of architecture", "college of engineering", while students in all colleges may live in the same dormitories- that is, the "colleges" center on subjects, not student. Oxford, Cambridge, and English universities in general, have colleges based on living quarters with, say, Literature, Math, etc. course offered at the lecture halls of each college though upper level classes may be taken at which ever college has specialists in that field.
Although I have never attended an English university, my understanding is that lower level courses, at least, tend to large lectures by "professors" with additional individual tutoring by "tutors" who work for the university (not our, American, concept of "free lance" tutors). And upper level and graduate courses may be entirely "individual tutoring".
