Did bad grades from high school affect you?

The beautiful thing about education in the USA is that there is almost always a path to redemption. Bad grades in HS? Go to CC, get good grades there, transfer to a 4 year U. Bad grades in the 4 year U? Go back to school, take a few extra classes and get good grades, then go to grad school. You can do nothing about your past, but you can always change your future.
