I don’t know that grit can be all that well-rewarded, though, under the current system. My daughter is in a community college math class (mostly math or CS majors). It is notoriously difficult. Her dad took the class recently in CS grad school at an Ivy and it’s too hard for him to help her with it. Most students have withdrawn. Of the less than ten students left she knows over half are taking the class a second time and praying to get a C. She is praying to get a C. Having learned a hell of a lot and failing to weed out probably won’t help her when she goes to apply for four year colleges, though. In the end, though, what you learn for yourself and about yourself is really all you have post-graduation.
