Worst I ever did was 24 credit hours in a semester. That was the fall semester of freshman year. It was also the highest gpa I ever got (only one B). By Spring of senior year, I was down to 12 credits, and the worst gpa of my undergraduate career.

I guess I work best when I'm stretched a little.
BTW, the degree was in Applied Physics. I was the first and only person to graduate from CWRU with that degree. They cancelled the program the year after I granulated.
