I am new in the US so i Have no idea about the grading system. I received a 4.0 GPA and I have no idea what this means. Is it good

regular Classes are out of 4 points, AP/IB/Honors will give u 5 for A

A-4 points

B-3

C-2

D-1

F-0

add one to your points if its an AP class, so A=5, B=4 etc.

GPA is the average of all the points you got in your classes, so a 4.0 would mean you have all As in regular classes or have Bs in some APs, which is pretty good.
