Fascinating. Lots of this seems familiar - my daughter once spelled Mississippi without a single S. On a test, after they'd been working on it in class. DD8 often spells 'she' as 'hse'.
DD12 seems to be getting by just fine now, though she vaguely wishes she read faster and still prefers audiobooks/being read to over reading on her own, especially for text that's more complex (high school vs 5th grade fiction). Are there guidelines for when compensation is good enough, and when dyslexia should really be remediated?
