The thing is that she is not really academically challenged at her current level. She progressed the most with her handwriting and coloring.

Probably she would have 3 of her friends including her current BFF in the public school with her. Compared to her year older friends she is either at the same level or clearly ahead. She is still 4 but will turn 5 this summer, I think we need to test her next winter although I'm not sure which test they will ask for the early entrance in public school.
