As a U. of C. student I always took four courses each quarter and recommend this for any kid focussed on the experience of learning. You never know in advance what course is going to be a revelation and a life-changer, so why scant yourself on the chances of finding as many of them as possible in a very finite undergraduate career? Why pass up a chance to learn fascinating things you’ll never have another chance to learn? Why omit even one perspective a brilliant Chicago prof might bring to an otherwise superfluous subject matter?
It’s a good idea to choose judiciously. If, say, you’re taking a course in Dickens (one very fat novel per week) you had best pair it with a course in the Metaphysical Poets (a handful of poems each week).
Summers really ought to be for doing something other than course-work. That ought to be down-time from the rigors of the school year. If you are working summer jobs, as I did, you really feel the intellectual vacuity of your life and really anticipate the charm of going back to school come the Fall. Likewise, l would think, if you are travelling or simply hanging around and desultorily reading.
German is a tough language. I had no high school background in it when I took it in College and made the poorest marks I ever made in any course, barely scraping through. Yet I enjoyed the experience and don’t consider it a loss (nothing is ever really a loss). I have from time to time returned over the years to this or that piece of German writing with dictionary in hand. Though the vocabulary is elusive, the syntax and sound somehow got into my head and modified it accordingly. I always encounter the German tongue as an old friend incompletely understood.
