OP- I am no expert here just a mom of a senior and sophomore. My two cents-
I would consider meeting with a school counselor that is more familiar with the school and courses provided at her school and give your daughter a challenging but balanced schedule. She seems to be motivated and excited to start high school but in reality this is just the beginning. Working too hard too early may be counterproductive in her future HS career. She may end up being burn out early and not do so well later on. She should also find an outlet to enjoy being a teenager, a sport, instrument, a club- anything- that she truly enjoys regardless of how it would look on her college application. Best of luck!
