Help, Grading Scale and weighted classes

I’m just curious to how the grading scale and weighted courses varies among different schools, just post how your school works,

heres mine:
A: 94-100 B+:90-93 B: 84-89 C+: 80-83 C: 74-80 D+: 70-73 D: 64-69 F: <64
The only weighted stuff is AP classes which are + .5, so the highest GPA a student at our school could get with straight A’s and a lot of ap classes is about 4.3, usually the highest is between 4.1 and 4.2

Oh yeah, my school has honors courses, but no extra weight is given to them, yup, it sucks
