I went to U of C and actually found years 3-6 to be better than the first and second. First year I was in Science and hated it. Second year I switched to engineering and had a bit of trouble figuring out the balance between partying and studying (the "weeding"... it is real).
But by the 3rd year I had the balance figured out, so I could party whenever I wanted and still stay on the Dean's list for grades. The internship/work term year was probably the best though - you start making money but you really have no responsibilities yet, no studying to worry about, and you're still young enough that you don't care about coming into work hungover all the time.
