High school GPA is pointless, all that shows is that you did what you were told, and didn't see the bigger picture and understand that they are trying to turn you into a laborer. I had a low GPA but I got a 21 on the act, meanwhile all my friends who were 3.95-4.0 got 13-16. It really comes down to how a individual will handle a uncomfortable situation, and there day to day work ethic. And of course communication skills.
