Hm...I would say that she isn't THAT much of a genius. More of an innovator, really. I would make her...one year older then? With the main reason for her grade-skipping being that, due to having a special Connector type, she would have to partake in more advanced classes. While she goes to the same homeroom and Connector-focused classes as Year 2 peeps, she would go to accelerated classes for academic subjects such as English and Math.

Something like that, at least.

EDIT: Heh, another Moon Goddess nice gurl.
