My guess is that this child is a genius at pushing your buttons. (Mine definitely know which buttons to push to make me crazy). I’d say to drop all college talk until the spring semester of her junior year. She’s probably not ready yet and is perhaps intimidated/scared she won’t get in.
She sounds very mature in her approach to her schoolwork and activities, so I would do my best to stop mentioning college and let it ride for the next several months.
Good luck - and remember that most all kids drive their parents crazy at some point when they are growing up!
