OP - Don’t stress. You are doing just fine in challenging courses!
@Nhatrang @MWolf Doesn’t the GPA implication depend on this particular HS’s grading scale? At my D’s HS a 92 was a B+ and weighted as a 3.3.
That said, OP - even if that is the case for your school, the grading scale would go with the transcript so there would be context for colleges.
