Thank you for the links and books I will check those out. She is not challenged at school but acceleration is not an option where were are (not in US). Her class is very bright I think bottom of the class is really high average.

By nature she is not really competitive, she actually hates any kind of competition but seems to think that it is important to be top of her class. Like I said the school does not make a big deal out of it, there is no price or diplomas or nothing like that.

We always tell her that she should just try her best (maybe this is bad as well, as she thinks her best needs to be perfect) and we are not interested about her grades.

Violin has been really great for her as she has been able progress on her own speed. She loves her lessons and never gets upset when teacher is correcting her.
