Because despite her nice IQ she is underachieving big time! Would you believe that she claims she cannot count more than 20???
She can add or substract in her head (small numbers), deduced all by herself that n+0 = n, understands the concept of multiplication and division, fractions....
But counting more than 20... is too difficult for her

Her vocabulary is as well smaller than one would expect for such an IQ. She does have a big vocabulary... spread over 4 languages! Spanish is the strongest but she lacks a lot of cultural exposure to it, and I think this would be reflected in the test.
SO I was thinking if it would be a good idea to work on those issues first before any further testing.
