Just thought I'd throw my two cents in. I know that in my own case in school...I spent a lot of time able to guess the answers. In fact I graduated from school never really learning to study effectively. I was certainly not achieving high grades despite the fact that I was in AP classes and gifted pull out all through school, including some college level courses in high school. I didn't lack motivation as much as I feared failure. I actually felt I didn't deserve the gifted label and felt at some level out to prove just that. I was frustrated at why I didn't know all the answers automatically, but also felt I didn't want to put all the time and energy into learning something the "hard" way.
I'm not sure if any of this makes sense, but it's the best I can remember of myself.
Now in my daughter, I see the path in which she's headed and I wonder how to help her. She learns easily and is tested at 5 years above grade level in reading and comprehension and 2 years above grade level in math. It's easy to see that when your that far ahead of your peers, you don't learn to learn.
Your daughter is born primed and ready to learn, she just new at it being effortless.
I love all the response you've had, this board is so informative.
