The problem is, without knowing the cap on "bonus points," I can't know how far under 4.0 your GPA might have been without the bonus. Maybe your GPA was "only" a 3.7 before adding 1 bonus point? It's ambiguous at best, deceptive at worst.
On the other hand, if a school doesn't give extra points for more advanced classes, someone who took the hardest curriculum possible and did pretty well might have a lower GPA than someone who took the easiest curriculum possible.
