When you say "schoolgirl" do you mean 5 year old or 15 year old? I'm assuming that she's at a boarding school or similar? This makes a pretty big difference to the story and it's the sort of thing that a reader will struggle to visualise if you're not more specific.
yqwertz's feedback is great. I agree that the I.I. and the goal are currently just simply too broad. I struggle to visualise any of it because there seems like so much for her to do and I don't understand how a schoolgirl has the ability to do all of that.
yqwertz's version is really good. I would take that as a starting point and adapt that into the story you want to tell. Narrow the scope and give us some more specifics.
Definitely think there's a story in here though so stick with it!
Hope this helps.
