I've taken courses whereby, given the exams, homework, and textbook, a student could pass the course with little class interaction.
Which undergrad or post-grad level courses can be self-studied and still develop a similar understanding and appreciation as that of a traditional course? For example, maybe the first three undergrad Calculus courses, whereas a first or second course in Linear Algebra might have proofs which greatly benefit from a live professor's explanation as opposed to a textbook.
