I agree with everyone else that this level of discrepancy between one’s expected and actual GPA is odd, but I do think it is worth a reminder that students and parents need to check the school’s calculations periodically. My daughter’s school incorrectly weighted (well, didn’t weight) her grades from DE classes. It took me months of pestering her GC to get it fixed (and she responded only because I finally cc’d the principal). I am positive that her final GPA, whatever it is, is incorrect, but at least the GPA submitted with her college app was close to correct.
