My daughtee and I did a 2nd year math course at college in San Diego. We has a book, self-learnt, then did the tests, then did the next lesson.
At one point, a math tutor told me he had a masters in math, and he had never seen anyone do math the way my daughter and I did.
It was not unusual for us to learn the principles in a few hours, to sit aan hour test, do it in 30 minutes, and get 100%. It was like that for every test.
When I tell people it's impossible to be gifted wwithout being able to do math, they get angry with me. So I have learnt not to mention it. When I tell them that math us an exercise in logic, they tell me they can be logical but still not understand math. Not true. It's a matter of degree.
Thank you for your confirmation.
