"There are marathon runners, and there are sprinters."

That's the best way I have heard it described yet. I busted my butt both through undergrad and graduate school and I was always in the middle curve, never the top, but I did pass some of those that started in the top.

I'm not more tired with less to do now that I am out of grad school, but I filled the time up pretty good once I got it back.

Good luck with the end of classes and the bar.
