0.1% had GPA from 2.5 to 2.99, and 0.1% had GPA from 2.0 to 2.49. 
[That last one is curious.]

Two possibilities I can think of:

• the smartest guy in my public high school -- arguably the smartest guy I have personally known -- was a C student.  He was so smart that he was bored and didn't bother to turn in homework.  His artificially low GPA made him the secret weapon for the Academic Decathlon team which required a mix of A, B, and C students.
  
• maybe the person was a late bloomer like this guy who wrote a Stanford Daily article about being a 30-year-old freshman after getting kicked out of the Navy.    (He has several other short pieces worth reading as well.  Click on his byline to get to them.)
