I think it’s hard for colleges to use weighted gpa’s since high schools weigh differently. At our NJ HS I believe the highest weighted GPA is a 4.4. My daughter had a B, a few A- (our school tops out at A, no A+), 9 AP’s, the rest honors, 4.2 wgpa, unweighted was around a 3.95. Colleges can determine rigor by looking at the transcript and courses taken.
