Just that really. My MIL says SIL was tested age 7 at school (we are based in the US) and was told she had this IQ. Mil kept it quiet from DS - my now DH - in case he felt inferior with his 140 plus IQ. But my MIL was later told SIL was dyslexic because she wasn't getting on at school; this was in the UK as they both went to school in the UK for a while. But SIL was and is a good reader - she sometimes misspells too and to and their and there but has a good job. She didn't do A levels in fact fought against doing them and went to a technical college instead. My cousin who is a member of Mensa (and quite an oddball it must be said) has this IQ and argued with me that either SIL was badly let down by the education system in both the US and the U.K. Or my MIL's memory isn't all it should be. or are IQ tests just pants?
