What does it mean to have a 4.0 GPA?
th: The letter grades A and A+ are equivalent to 4 "grade points."  A- is 3.7, B+ is 3.3, B is 3.0, B- is 2.7 and so on.  If someone has a 4.0 this means they received an A/A+ in every class.Depending on the university and the professor, this can mean different things.  If the class is curved, one third of the class will probably receive A-/A/A+ range grades.  If the class is not curved, anywhere from 85% to 95% may be considered an A depending on the professor, class, and university.  Most commonly a 90% range is considered A- and up and 80% range is B- and up (assuming no curve).The overall GPAs themselves are usually calculated by taking specific units of each class into account to give some classes more weight than others.  For a 4.0, all grades must have been A anyways so this detail is insignificant.3.7 and 3.5 are often considered very good GPAs in university.  Receiving an overall 4.0 GPA is fairly rare at many schools as an receiving even one A- or below would ensure less than 4.0.
