I infer "liberal arts" as English, no?
I share the same discontent you've lamented about regarding school. My parents mandated that I would receive a University education. Half of the time, my interest waned; the other half, my interest piqued. I view my degree as a 'pratical' physical manifestation of 'knowledge' in the world; yet you and I both know that accumulating knowledge functions like a continuum rather than a discontinuous block (Of course, the latter proving true when death ends life). A degree is not a sarcophagus nor an effigy for knowledge. For me, my University experience lied in Professors connecting, caring and investing time into you. That alone made my University experience worth it.
If the problem lies in the classroom setting, try some 500/5000 level courses. Its Level of discourse far surpasses antecedent course levels. That's a small start.
Clover, I sincerely hope you find at least one professor, to whom you can connect with on some level.
