In every other area I haven't done the best at I can basically still fix except this. Do NOT graduate college with a low GPA. If you're not doing well, slow down, take time off, whatever you need to do.
Even if you think it won't matter right now, you never know what is coming later on. Want to go to law school ten years later? By LSAC regulations, law schools have to use your first undergraduate GPA in calculating admissions. You could get a second bachelors degree. Nope, still have to use the first one. Sure, the schools say they consider experience, blah blah. But when it comes down to it, they (and everyone else) are rankings obsessed, and they're not going to let you drag down their average.
Same basic concept applies to MBA, MS, MA, etc.
