My first college (of 3) was on a quarter schedule. One week off in between except after summer which was like 10 days. I did study, but I also had two jobs in college, I worked pretty much full time and class full time. No rest whatsoever. But I didn't want to stop when the time came, I wanted to stay there as I loved it there. Best days of my life, many of them. No frats, just learning.
I learned so much and I've forgotten so much. I hope one day science will improve the human memory, some day soon. And I hope that they improve how long one's IQ stays intact. It's not fun being old and stupid, hah.
