Why not to go to graduate school
"...um, well, no." Here's why:
As the statistics go, you probably have many other equally good if not better things to do with your education than go to grad school. You may not have seen some of the other options for developing your life trajectory past Grinnell College.

And while we're at it, consider reflecting on what you do want out of life.
For all that, maybe you're curious why anyone should consider going to grad school after Grinnell College?
