AEH will have better info but although IQs can be unstable when young it is more likely in my opinion your health issues, ASD and maybe another undiagnosed learning disability have caused problems. If you can get an A in a high school class if you try (assuming an academic class) then 90 is probably not an accurate score. Did they do a gai?
It was high 90s, I don't think they did a GAI, but I estimated that it'd be slightly higher than the FSIQ, maybe by a few points with the lowest index score taken out (the PSI).
The high school I went to wasn't a "rigorous" high school, it was a public high school in a not so nice neighborhood, so I think they were lenient with grading. I had a shortened schedule in the term where I got all A's, with 4 classes, all "academic", but I slept through a lot of class time, due to the sleep disorder.
