Regarding her points:

  1.  No one has ever asked about my GPA.

If college is your terminal degree and you know you will never apply for a higher degree, that might make sense.

  2.  I didn't sleep.

One would hope that not getting straight A's wouldn't induce sleep, but instead would free up time to do more fun/cool/enlightening things. You'd still be sleep deprived.

  3.  I've forgotten 95% of it. 

Not sure that college is designed to impart information.

  4.  I didn't have time for people. 
  5.  Work experience is more valuable. 

These two seem reasonable.
