I feel your pain @kunjiBoy. DD is graduating a year early from HS with 80 College credit hours. My advice to you is about priorities.
Every family and child is unique…figure out what works for you!
Knowledge without context has little value. Help her to persue the things she is passionate about and try to give her chances to explore her passion with wise and capable mentors. We used NUMATS at Northwestern in 6th grade and really loved it but our greatest single experience was the first time D stepped into the library at Kent State (our local public research university) it was the “kid in the candy store” moment! She started with independent projects in classics under the supervision of a grad student arrainged by the school of educational. Moved onto botany and finally psych (her team is writing and hoping to publish a 5 semester metacognition study this semester.)
Along the way she has had incredible professors, outstanding administrators both at her public high school and at college.
For us, and I am guessing for @forensicator15, extracurriculars like debate, played a big role in meeting D need for academic challenge while still letting her progress socially with her peers. As she grew, she shifted farther and farther toward college classes and peers.
At 17 she has really exhausted the opportunities here and is matriculating to a very rigorous college hoping to complete an advanced degree in 4 or 5 years which still gives her a chance to explore an “undergrad experience” and gain maturity.
Try to remember its up to your family to determine what constitutes happiness and success for you. She is more than just a test score or a gifted student. And happiness and success have a lot to do with being well adjusted and feeling loved and cared for.
Best of luck
