Wait what? Why would it make people retarded to be confused by "94 GPA". It is not a conventional way to state your GPA or if it is now it wasn't for many of us that are older. When I was in school GPA went to 5.0 or 6.0 max (For highschool and only if you took honors/AP classes) In college it is always on the 4.0 system that GPA has always been.
It is not retarded to be confused by something that doesn't make any sense. You have some serious issues if you feel the need to call people retarded because the OP decided to state his GPA in a non standard way.
